I discovered a Fossil on the Seaside and Puzzled
Up to date on March 22, 2017 Kathi moreContact Creator Discovering Frequent Fossils on Nice Lakes Beaches
A favourite past time for a lot of is combing the beaches for attention-grabbing gadgets the surf washes in. Whether you’re strolling along the shoreline of the ocean or the nice Lakes within the USA, your imagination is on high alert to choose something up you just cannot cross by! Out of the blue, one thing catches your eye! But, it is not driftwood or seashore glass and even a pretty rock. You might not know exactly why, but you suspect you found something that was once a dwelling creature.
Has this ever occurred to you A deep sense of curiosity and childlike imagination drives us to search out out what we may have picked up alongside our saltwater or freshwater shorelines. Having collected quite just a few samples from Lake Michigan’s shoreline, myself, I finally decided one day to meet my nagging curiosity and followed via with a rewarding investigation. The more I learned about my stony sand-smoothed findings, the more I needed to know. I questioned what the creatures might have regarded like when alive and how they survived. I also wanted to know how they confirmed up so prevalent alongside the recent water beaches. A while later, after many answered questions, I can honestly say I get pleasure from a cool interest. Taking issues a step additional, I’ve drawn illustrations of their dwelling beings and started a fossil site. You’ll find the link at the top.
A few of essentially the most prevalent fossils found alongside the great Lake’s beaches are crinoids (shown in the pictures to the suitable). They have been coined with a a number of names because of the animal’s options and by the character of their fossils found throughout history. One common name for them is “Indian Beads”. Native People have been identified to make necklaces with their broken up pieces which resemble the shape of beads excellent for stringing. They’ve also been referred to as “Fortunate Stones”! Spotting one takes a eager eye as a lot of the pieces are quite small.
As dwelling creatures, each circular section was stacked one over the opposite constructing the animal’s complete framework. They possessed branching arms that sat atop lengthy single stems. They had been sessile creatures, in other phrases, they remained connected to the sea floor. Some varieties are known to have towered a number of meters in size. Their unfastened structure resulted within the residing organism’s beautifully coloured and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny food particles passing by on ocean currents with their feathery network of arms that functioned like traps. Crinoids match into the phylum of Echinoderm, which means spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s prolonged historical past began in the course of the Ordovician Interval round 500 million years ago, though most fossils are from the Mississipian Period round 345 mya and are preserved in limestone. Right this moment there are far fewer species and most lack the lengthy meandering stem frequent in Paleozoic varieties.
Within the course my investigation, I had usually questioned why so many crinoid fossils ended up along the nice Lakes; notably by the fact that they had thrived in saltwater environments. I’ve since discovered they are often found widespread in North America. Part of the answer to my inquiry is straightforward sufficient to clarify. Throughout their lifetime, a lot of the world’s continents have been coated below heat shallow oceans, together with elements of North America. So how is it their fossils are so widespread close to the massive lakes The reply is because ten thousand years in the past when the large glaciers sculpted the deep basins forming the nice Lakes, in addition they dug into the deep layers where their stays rested. In the method, they had been deposited the place we now can uncover them and revel of their secrets and techniques, as well as that of different species from the identical period.
One other common beach discover, bryozoans are often known as lace corals due to their delicately threaded look, however they don’t seem to be true corals. Instead, they are moss-like animals belonging to the family of Fenestellida for his or her fan-formed, mesh look. They reside in tight colonies sculpted by onerous, limy, branching buildings. The colony consists of thousands of particular person animals known as “zooids”. Each individual zooid lives inside its personal limy tube known as a zooecium. The zooecium are the scale of sewing needles. A single zooid begins the colony. A bryozoan colony has been observed rising from a single zooid to 38,000 in just five months. Every further zooid is a clone of the very first one.
Fascinating how they feed, Each zooid has an opening by way of which the animal can lengthen its ring of tentacles called lophophores. Their lophophores seize microscopic plankton from the water passing by. If one zooid receives meals, it nourishes the neighboring zooids because they’re joined by strands of protoplasm. If solely we people might be extra like them making certain everyone on the planet is fed!
Their fossil report dates again 500 mya with 15,000 identified species. As we speak there are about 3,500 residing species.
I discovered these clam fossils on the shore of Oval Beach in Southwestern Michigan. The shell of the darker sample has been fully replaced by minerals and is petrified to stone. Its easy floor is a telltale demonstration of the lake’s sand and water action. The lighter coloured sample clearly reveals the hardened muddy sediment that has utterly encrusted its shell.
“Clam” generally is 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 collectively. Every kind lack a head and often have no eyes, though scallops are a notable exception. With the use of two adductor muscles they’ll open and shut their shells tightly. Very fittingly, the word “clam” provides rise to the metaphor “to clam up”, that means to cease talking or listening.
Bivalves have occupied Earth as early as the Cambrian Period 510 million years ago, however they were notably considerable through the Devonian Period round 400 million years in the past. Their fossils are found in all marine ecosystems and mostly in close to shore environments. In 2007, off the coast of Iceland, a clam was discovered to be at the very least 405 years old. It was declared the world’s oldest dwelling creature by North Wales, Bangor University researchers.
No other organisms typify the Age of Invertebrates greater than brachiopods. They’re probably the most abundant Paleozic fossils, except for perhaps trilobites. Paleontologists use them so far rocks and different fossils. Countless billions accumulated on the ocean floor with over 30,000 forms. Immediately there are far fewer species, only about 300 which live mostly in cold water, deep ocean environments.
Brachiopods appear to be clams however are very completely different inside. To tell them apart, clams have uneven shaped shells, however each top and backside halves are similar. Brachiopods are symmetrical at a glance, but the bottom shell is smaller. Brachiopods are generally known as “lampshells” as a consequence of their similarity in shape to a Roman oil lamp.
They reside in communities connected to objects by a muscular foot called a pedicle. They pressure water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
Through the Devonian time slot, over 350 million years in the past, Michigan was coated by a shallow saltwater sea. That’s the place mass colonies of corals known as Hexagonaria, percarinata, commonly referred to as Petoskey Stones, thrived and flourished. The saltwater seascape should have been lit up with a quilt-work of colors by the mass colonies. Sadly, they turned extinct at the tip of the Permian Period’s mass extinction.
The name “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan metropolis was named after him, solely the identify was modified to Petoskey. Because of their abundance alongside Michigan shorelines, particularly in the northern regions close to Petoskey, Governor George Romney signed a bill in 1965 that made the Petoskey Stone the official state stone.
When observing one of the fossils, every coral hexagon construction, visible to the attention, held a single animal which opened a mouth to expose tentacles. The tentacles took in food and were also used to sting any organism or other corallite that came too shut. Calcite, silica and different minerals replaced the original corallite exoskeleton.
An extinct order of coral known as tabulate corals also formed reefs and lived in heat shallow waters during the same period as the Petoskey Stone corals. They had been the favosite corals. The tabulae (horizontal internal layers) had been constructed outward as the organism grew. These layers can clearly be seen within the photo to the fitting. The favosites may also be identified by the honeycomb pattern on the exterior of their fossilized stays.
Hope you’ve enjoyed my fossil discoveries. Subsequent time you go to the seashore, keep your eyes open for a fossil discovery of your individual. You are welcome to use my hub or visit my fossil weblog to assist make an identification!

Nice introduction to fossils and fossil attempting to find novices Kathi.
I like the line:
‘A deep sense of curiosity and childlike imagination drives some of us to search out out what we picked up along the freshwater shoreline.’
That’s the unfortunate point I feel. For some motive, as people grow 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 night time sky. That is unhappy – if only everybody may keep that sense of curiosity and imagination as they develop up – the world can be a much more wondrous place for all – adults, in addition to kids.
I hope some at the least feel impressed as they walk along a shoreline or beside a cliff face, to show over a couple of stones and see what they’ll discover. Alun

Yes, Fossillady, I did enjoy this. This has been an afternoon of learning. I have learn so many fascinating articles this afternoon and this one is definitely one I’ll remember. I had no idea. It’s amazing how a lot there is to study fossils.
Sending many Angels your way this afternoon. 🙂 ps

Hey this is so cool i simply bought my first fossil and wana talk with individuals abot these things . somebody text me stone island sale manchester haha
Hey Micky, good to see you, sorry so late as I have been so busy recently with new jobs and all! I miss the regular contact with all my hubber associates! Thank you for the nice remark, you are very type to say so! Hope all the pieces is great with you! Hugs my good friend

Your hubs are so pretty! Thank you pricey Fossillady!
Ha, What have you learnt, I’m a geo-jokster and do not even know it…hee
Ha fossillady something new…LOL and have been speaking 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. Interesting.
I am fairly positive the accretion traces on the top of a clam will reveal its age-like the rings on a tree the clam gets larger and one other ring is added-

I will speak fossils with you any day. I am in contact with each sides of my mind! Generally I shock myself, lol.
“In 2007, off the coast of Iceland, a clam was discovered to be at least 405 years previous. It was declared the world’s oldest dwelling creature by North Wales, Bangor University 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 move Oh, I believe a poem just came to mind. Each sides of that brain are reacting at the same time.
Thanks for an incredible and effectively researched Hub.
Very kind of you Janet! I had by no means worked with pastels earlier than so there’s plenty of room for improvement, they are principally targeted for kids! Next time you are on the seashore or in nature I hope you may recognize a few of these fossils!

Very fascinating hub,Fossillady !Very informative and I like the artwork! It’s awesome.I by no means knew a few of these had been fossils! Properly,I certain realized something tonight!
Thanks for sharing both information and art…good combo!
i do know its kinda humorous I at all times favored Ross too and my wife would always take a look at me when he would say one thing geological…
don’t fret- put up a fossily hub i’ll read it…
ya obtained one fan…its a start
I do know what you imply, no person wants to talk about fossils with me both. Jogs my memory of Ross on Associates. He at all times desires to share his details about fossils and the others will not have something to do with it!lol
I’m just glad to talk fossils ith someone- my children likem however.. even they tire of looking fast
Nice recommendation Tom, Very much appreciated!
When cleansing crinoids- ya gotta know what kinda rock is clinging to them- is determined by the rock sort you findem in round here it iseasily found in shale i usually rtry to clip off- one of the best i can with toe nail clippers – watch out- then i will use a reasonably dilute HCL resolution between .1 and .25 dilute-use a “comfortable wire brush” possibly nylon brush-ajust hcl to rockhardness- all the time use acid in wellventilated space use safety glasses and neoprene or nitrile gloves- sandstone embeds- could be picked off the crinoids and a ultimate acid wash
Hi Workingmom, Good to see you here! I want I had advise for cleaning fossils, I would think as long as you do not use anything too harsh,it is going to be okay!
It feels like it’s not all that tough for you to search out the crinoids where you’re! I get so excited each time I can spot one! lol…take care!

Love this hub! I was really enthusiastic about writing a hub about crinoid beads (actually about using them to create jewelry, since I try this). My husband is an newbie archaeologist (aka rock hound), and he started taking me with him once we first began courting. I did not care a lot about discovering the arrowheads that he was looking, but I fell in love with the beads! We have been simply down in Monroe Co.KY, and located fairly just a few inside a couple of minutes by some of the many creeks. By the way, are you aware an excellent technique for cleaning fossils I need to clean these beads if I’m going to make jewelry out of them!
Hello Tom,Oh it seems like a rick fossil find area. I have never found a trilobite, my husband did as soon as while engaged on the railroad. I like to seek out crinoids which can be still attach, but it would be even better to seek out one totally intact! Thanks for stopping by!

We’ve the sme devonian aged fossils close to Lake Erie- that shallow sea was actually large when my son went looking with me he said what are all these nuts and washers doing here-on the ground in fact we had been in a crinoid rich area. There were a ton of Brac’s s well-then we discovered some smaller trilobite halves and a had an incredible time diggin the dirt and shale shards He kept pulling up shale and asking what it was then he gave me one with a Trilobite trace fossil (imprint) it was actually a superb one
Hi WillStarr, You made your children really feel very special that day! A beautiful fatherly factor to say. I might like to go to Kentucky and check out the shale bank. Kentucky has several fossil websites I’ve examine! I recognize you from different hubs and that i see you are now following me, right back at ya!

The Kentucky farm the place we lived for just a few years had a shale financial institution on one side of a stream that was loaded with fossils. My youngsters have been fascinated once i instructed them they have been trying at the beginnings of life on Earth, and that their eyes have been the first human eyes to ever see what that they had discovered.
Nice, I am glad you made a new discovery, I hope you find lots of fossils! It actually is enjoyable when you find one! It is gratifying later when you’ll be able to identify it!

Wowwee! Nice hub. I dwell in Long Island New York, the place there are miles and miles of beaches. I never knew some of the issues I was taking a look at might be fossils. When the weather is hotter I’ll revisit your hub to look and be taught more. Thanks for educating me. Rated up and awesome.
My jaw dropped while you talked about coelacanth fish that was discovered! I’ve read that too! I might love to come there and fossil hunt. I’ve never been throughout the ocean. Hope to try this earlier than my day comes around!
Nell Rose 6 years ago from England
Hello, you must come over to England, you’ll have an incredible time! lol the last time I went to Lyme Regis, Jurassic coast, they had been filming for Tv, and they’d a fossil programme full of all that they had found, I’d imagine that there are nonetheless loads of what we imagine to be extinct animals nonetheless out there dwelling in the deep ocean, I remember reading that fishermen discovered a coelacanth fish nonetheless residing again in 1933, and that i consider they have caught a few more since then, so you by no means know! cheers nell
Properly, you’ve gotten made my day and i hope yours is crammed with love and joy! Hugs

As a matter of truth I’m engaged on one partly because of your encouragement! It is much appreciated!
..Hiya Kathi – sure I love to stroll alongside my seashore within the spring, summer season and fall and pick up ‘discovered objects’ and flotsam and jetsam washed in from the tide especially after a storm or excessive winds however as I communicate there is so much snow and ice down there proper now you cannot see something besides an enormous blanket of white – everywhere you look – I imagine I could have to attend till the spring now to find something new and get back to my days of ‘beachcombing’ …….if you have any extra photographs about your days on the seaside or simply around where you reside it could be good to see you make one other photographic hub on that topic ……

I am unable to assist but really feel sorry for poor deaf kitty, however I am certain he/she’s in good hands. We’ve the same lake impact on the west coast of Michigan brought on by the westerly winds. Actually we’re in a snow belt space. Final couple of years we’ve had document snowfall over one hundred twenty inches. Do you pick up fossils when you stroll the seaside Thanks again to your help!

…absolutely fascinating hub topic you’ve written about right here …. I reside on the northern shores of Lake Erie in Ontario, Canada and i stroll on a regular basis alongside my seashore with my deaf cat (on a leash). I stay one hundred toes away from the lake ……and that i always see flotsam and jetsam and located objects which are washed up every day whether or not it’s man made or miracles of natures.
By the way how is the weather where you reside
We often get what is named lake impact circumstances due to the winds off the lake.
Once more you may have actually completed some wonderful analysis here on your hub and would be a worthy addition in any classroom!
