I discovered a Fossil on the Seaside and Questioned
Updated on March 22, 2017 Kathi moreContact Creator Discovering Frequent Fossils on Great Lakes Beaches
A favorite past time for many is combing the beaches for attention-grabbing gadgets the surf washes in. Whether you are walking alongside the shoreline of the ocean or the nice Lakes within the USA, your imagination is on excessive alert to choose something up you simply cannot cross by! All of a sudden, something catches your eye! But, it is not driftwood or beach glass or even a reasonably rock. Chances are you’ll not know exactly why, but you suspect you found something that was as soon as a living creature.
Has this ever occurred to you A deep sense of curiosity and childlike imagination drives us to find out what we may have picked up alongside our saltwater or freshwater shorelines. Having collected fairly just a few samples from Lake Michigan’s shoreline, myself, I finally determined one day to satisfy my nagging curiosity and adopted by way of with a rewarding investigation. The more I realized about my stony sand-smoothed findings, the more I wished to know. I questioned what the creatures could have looked like when alive and how they survived. I also wished to know how they confirmed up so prevalent alongside the contemporary water beaches. A while later, after many answered questions, I can honestly say I take pleasure in a cool pastime. Taking issues a step additional, I have drawn illustrations of their living beings and started a fossil site. You’ll find the hyperlink at the top.
Some of the most prevalent fossils discovered alongside the great Lake’s beaches are crinoids (proven within the photographs to the appropriate). They’ve been coined with a a number of names because of the animal’s options and by the character of their fossils discovered throughout historical past. One widespread name for them is “Indian Beads”. Native Individuals had been identified to make necklaces with their broken up items which resemble the form of beads perfect for stringing. They’ve additionally been known as “Fortunate Stones”! Spotting one takes a eager eye as most of the pieces are fairly small.
As living creatures, each circular part was stacked one over the opposite constructing the animal’s total framework. They possessed branching arms that sat atop lengthy single stems. They were sessile creatures, in different phrases, they remained connected to the sea flooring. Some varieties are recognized to have towered a number of meters in size. Their loose construction resulted within the dwelling organism’s beautifully colored and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny meals particles passing by on ocean currents with their feathery community of arms that functioned like traps. Crinoids fit into the phylum of Echinoderm, meaning spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s prolonged historical past started during the Ordovician Interval round 500 million years in the past, although most fossils are from the Mississipian Interval round 345 mya and are preserved in limestone. Today there are far fewer species and most lack the lengthy meandering stem frequent in Paleozoic varieties.
In the course my investigation, I had often questioned why so many crinoid fossils ended up alongside the good Lakes; notably by the truth that they had thrived in saltwater environments. I’ve since learned they can be discovered widespread in North America. A part of the answer to my inquiry is easy enough to elucidate. During their lifetime, much of the world’s continents have been coated under warm shallow oceans, together with parts of North America. So how is it their fossils are so common close to the massive lakes The answer is as a result of ten thousand years in the past when the giant glaciers sculpted the deep basins forming the great Lakes, in addition they dug into the deep layers the place their remains rested. In the method, they have been deposited where we now can discover them and revel of their secrets and techniques, as well as that of other species from the identical period.
Another widespread seaside discover, bryozoans are sometimes called lace corals because of their delicately threaded appearance, however they are not true corals. As an alternative, they’re moss-like animals belonging to the family of Fenestellida for his or her fan-formed, mesh look. They reside in tight colonies sculpted by laborious, limy, branching structures. The colony consists of hundreds of particular person animals called “zooids”. Every particular person zooid lives inside its personal limy tube called a zooecium. The zooecium are the scale of sewing needles. A single zooid begins the colony. A bryozoan colony has been noticed rising from a single zooid to 38,000 in just 5 months. Each additional zooid is a clone of the very first one.
Fascinating how they feed, Every zooid has an opening by way of which the animal can extend its ring of tentacles known as lophophores. Their lophophores capture microscopic plankton from the water passing by. If one zooid receives meals, it nourishes the neighboring zooids as a result of they’re joined by strands of protoplasm. If solely we humans could possibly be extra like them ensuring everyone on the planet is fed!
Their fossil report dates back 500 mya with 15,000 identified species. At the moment there are about 3,500 residing species.
I found these clam fossils on the shore of Oval Beach in Southwestern Michigan. The shell of the darker sample has been utterly changed by minerals and is petrified to stone. Its easy surface is a telltale demonstration of the lake’s sand and water motion. The lighter coloured sample clearly reveals the hardened muddy sediment that has utterly encrusted its shell.
“Clam” could be a term that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s surface. Bivalve oysters and mussels attach themselves to onerous objects and scallops can free swim by flapping their valves together. Every kind lack a head and often haven’t any eyes, although scallops are a notable exception. With the use of two adductor muscles they’ll open and close their shells tightly. Very fittingly, the phrase “clam” offers rise to the metaphor “to clam up”, meaning to stop talking or listening.
Bivalves have occupied Earth as early as the Cambrian Period 510 million years ago, however they had been particularly abundant in the course of the Devonian Period round four hundred million years in the past. Their fossils are discovered in all marine ecosystems and most commonly in near shore environments. In 2007, off the coast of Iceland, a clam was discovered to be no less than 405 years old. It was declared the world’s oldest living creature by North Wales, Bangor College researchers.
No other organisms typify the Age of Invertebrates more than brachiopods. They are probably the most ample Paleozic fossils, aside from perhaps trilobites. Paleontologists use them to date rocks and different fossils. Numerous billions accumulated on the ocean floor with over 30,000 varieties. Right now there are far fewer species, only about 300 which stay principally in cold water, deep ocean environments.
Brachiopods appear like clams however are very different inside. To inform them apart, clams have uneven formed shells, however each high and bottom halves are an identical. Brachiopods are symmetrical at a glance, but the underside shell is smaller. Brachiopods are commonly referred to as “lampshells” due to their similarity in form to a Roman oil lamp.
They stay in communities hooked up to objects by a muscular foot known as a pedicle. They strain water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
Throughout the Devonian time slot, over 350 million years in the past, Michigan was lined by a shallow saltwater sea. That’s the place mass colonies of corals known as Hexagonaria, percarinata, commonly generally known as Petoskey Stones, thrived and flourished. The saltwater seascape will need to have been lit up with a quilt-work of colors by the mass colonies. Unfortunately, they turned extinct at the top of the Permian Interval’s mass extinction.
The title “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan city was named after him, only the title was modified to Petoskey. Due to their abundance alongside Michigan shorelines, particularly in the northern regions near Petoskey, Governor George Romney signed a invoice in 1965 that made the Petoskey Stone the official state stone.
When observing one of many fossils, every coral hexagon structure, visible to the eye, held a single animal which opened a mouth to expose tentacles. The tentacles took in food and have been additionally used to sting any organism or other corallite that came too close. Calcite, silica and other minerals changed the original corallite exoskeleton.
An extinct order of coral referred to as tabulate corals also formed reefs and lived in heat shallow waters throughout the same interval as the Petoskey Stone corals. They had been the favosite corals. The tabulae (horizontal internal layers) were built outward as the organism grew. These layers can clearly be seen within the picture to the proper. The favosites can be identified by the honeycomb pattern on the exterior of their fossilized stays.
Hope you have enjoyed my fossil discoveries. Subsequent time you visit the seaside, keep your eyes open for a fossil discovery of your personal. You are welcome to use my hub or visit my fossil blog to assist make an identification!

Nice introduction to fossils and fossil trying to find newbies Kathi.
I like the line:
‘A deep sense of curiosity and childlike imagination drives a few of us to search out out what we picked up along the freshwater shoreline.’
That’s the unlucky point I feel. For some purpose, as individuals develop out of childhood too many lose their childhood fascination for such issues as fossils, in addition to other wonders just like the creatures which reside in a pond, or the stars to be seen in the evening sky. That’s unhappy – if only everybody might keep that sense of curiosity and imagination as they develop up – the world can be a way more wondrous place for all – adults, as well as children.
I hope some a minimum of really feel impressed as they walk alongside a shoreline or beside a cliff face, to show over a few stones and see what they’ll discover. Alun

Yes, Fossillady, I did enjoy this. This has been an afternoon of studying. I’ve learn so many interesting articles this afternoon and this one is definitely one I’ll remember. I had no thought. It’s superb how a lot there is to study fossils.
Sending many Angels your approach this afternoon. 🙂 ps

Hey this is so cool i simply purchased my first fossil and wana talk with folks abot this stuff . somebody textual content me haha
Hey Micky, good to see you, sorry so late as I have been so stone island 9 straatjes busy recently with new jobs and all! I miss the regular contact with all my hubber friends! Thank you for the nice remark, you are very type to say so! Hope every little thing is nice with you! Hugs my good friend

Your hubs are so fairly! Thank you expensive Fossillady!
Ha, What have you learnt, I am a geo-jokster and do not even understand it…hee
Ha fossillady one thing new…LOL and were talking about fossil Ha that’s an ideal geo-joke…
Extraordinarily pleased with this dialogue Tom and Birdy, realized one thing new!!!!!
I guess it is like a tree with the circles. Fascinating.
I’m pretty sure the accretion lines on the highest of a clam will reveal its age-like the rings on a tree the clam will get greater and another ring is added-

I’ll discuss fossils with you any day. I’m in touch with each sides of my brain! Typically I shock myself, lol.
“In 2007, off the coast of Iceland, a clam was found to be at the very least 405 years old. It was declared the world’s oldest residing creature by North Wales, Bangor College researchers.” How do they know this and the place is the clam at now How does one determine the age of a clam that has seen centuries go Oh, I feel a poem just got here to mind. Each sides of that mind are reacting at the identical time.
Thanks for a fantastic and effectively researched Hub.
Very sort of you Janet! I had by no means labored with pastels before so there’s lots of room for improvement, they are principally focused for kids! Next time you’re at the seaside or in nature I hope you possibly can recognize a few of these fossils!

Very interesting hub,Fossillady !Very informative and I really like the artwork! It is awesome.I by no means knew a few of these had been fossils! Nicely,I positive learned Stone Island Jackets something tonight!
Thanks for sharing both info and art…good combo!
i do know its kinda humorous I always liked Ross too and my wife would all the time have a look at me when he would say one thing geological…
don’t worry- submit a fossily hub i will read it…
ya bought one fan…its a begin
I do know what you imply, nobody wants to speak about fossils with me either. Reminds me of Ross on Friends. He all the time desires to share his details about fossils and the others won’t have anything to do with it!lol
I am just glad to speak fossils ith somebody- my children likem but.. even they tire of wanting quick
Nice advice Tom, Very much appreciated!
When cleansing crinoids- ya gotta know what kinda rock is clinging to them- is determined by the rock kind you findem in around here it iseasily present in shale i often rtry to clip off- the best i can with toe nail clippers – be careful- then i will use a fairly dilute HCL answer between .1 and .25 dilute-use a “comfortable wire brush” perhaps nylon brush-ajust hcl to rockhardness- always use acid in wellventilated space use security glasses and neoprene or nitrile gloves- sandstone embeds- can be picked off the crinoids and a last acid wash
Hi Workingmom, Good to see you right here! I want I had advise for cleaning fossils, I would suppose so long as you don’t use anything too harsh,it will be okay!
It feels like it’s not all that arduous for you to search out the crinoids where you might be! I get so excited each time I can spot one! lol…take care!

Love this hub! I was truly fascinated by writing a hub about crinoid beads (really about utilizing them to create jewellery, since I do this). My husband is an amateur archaeologist (aka rock hound), and he started taking me with him when we first started relationship. I did not care a lot about finding the arrowheads that he was searching, however I fell in love with the beads! We were just down in Monroe Co.KY, and located fairly a number of inside a few minutes by some of the numerous creeks. By the best way, have you learnt a very good methodology for cleansing fossils I want to scrub those beads if I will make jewellery out of them!
Hello Tom,Oh it feels like a rick fossil discover area. I’ve by no means found a trilobite, my husband did once whereas engaged on the railroad. I like to search out crinoids which can be still attach, but it surely can be stone island 9 straatjes even higher to search out one absolutely intact! Thanks for stopping by!

We have the sme devonian aged fossils close to Lake Erie- that shallow sea was actually big when my son went looking with me he mentioned what are all these nuts and washers doing right here-on the bottom after all we were in a crinoid rich space. There were a ton of Brac’s s effectively-then we found some smaller trilobite halves and a had an incredible time diggin the dirt and shale shards He saved pulling up shale and asking what it was then he gave me one with a Trilobite hint fossil (imprint) it was actually a good one
Hi WillStarr, You made your kids feel very special that day! An exquisite fatherly factor to say. I might like to go to Kentucky and take a look at the shale bank. Kentucky has several fossil sites I’ve examine! I acknowledge you from different hubs and that i see you’re now following me, right again at ya!
WillStarr 6 years ago from Phoenix, Arizona
The Kentucky farm the place we lived for a number of years had a shale bank on one aspect of a stream that was loaded with fossils. My children were fascinated after i informed them they were looking at the beginnings of life on Earth, and that their eyes were the first human eyes to ever see what that they had discovered.
Great, I am glad you made a new discovery, I hope you discover a number of fossils! It really is enjoyable when you discover one! It is gratifying later when you possibly can determine it!

Wowwee! Great hub. I stay in Lengthy Island New York, the place there are miles and miles of beaches. I never knew a few of the things I was looking at may very well be fossils. When the weather is hotter I will revisit your hub to look and study extra. Thanks for educating me. Rated up and superior.
My jaw dropped while you talked about coelacanth fish that was found! I’ve read that too! I would love to return there and fossil hunt. I’ve never been throughout the ocean. Hope to try this before my day comes around!
Nell Rose 6 years ago from England
Hello, it is best to come over to England, you would have an important time! lol the final time I went to Lyme Regis, Jurassic coast, they had been filming for Tv, and they’d a fossil programme stuffed with all they had discovered, I might think about that there are nonetheless loads of what we imagine to be extinct animals still out there living within the deep ocean, I remember studying that fishermen found a coelacanth fish nonetheless residing again in 1933, and i believe they have caught a number of extra since then, so you by no means know! cheers nell
Properly, you’ve got made my day and that i hope yours is crammed with love and joy! Hugs

As a matter of truth I’m working on one partly because of your encouragement! It is way appreciated!
..Hey Kathi – sure I love to stroll alongside my seashore in the spring, summer and fall and decide up ‘found objects’ and flotsam and jetsam washed in from the tide especially after a storm or excessive winds however as I communicate there’s a lot snow and ice down there right now you can’t see anything besides a big blanket of white – all over the place you look – I imagine I could have to attend until the spring now to find something new and get back to my days of ‘beachcombing’ …….if you have any extra images about your days at the seaside or simply round where you live it could be good to see you make another photographic hub on that subject ……

I can not help however feel sorry for poor deaf kitty, however I’m positive he/she’s in good palms. Now we have the identical lake effect on the west coast of Michigan brought on by the westerly winds. In actual fact we’re in a snow belt space. Last couple of years we’ve had record snowfall over one hundred twenty inches. Do you choose up fossils while you stroll the seashore Thanks again for your support!

…absolutely fascinating hub topic you have got written about here …. I reside on the northern shores of Lake Erie in Ontario, Canada and that i walk on a regular basis along my seaside with my deaf cat (on a leash). I live one hundred ft away from the lake ……and i at all times see flotsam and jetsam and located objects that are washed up on a daily basis whether or not or not it’s man made or miracles of natures.
By the way how is the weather the place you live
We frequently get what is known as lake impact circumstances because of the winds off the lake.
Once more you’ve got actually executed some great analysis right here on your hub and can be a worthy addition in any classroom!

Very cool hub , I have a good friend I am going to show this to. They’re most likely on the seaside right this minute on the west coast accumulating shells as I write this!
