i just have to know!! Favourite fossils / fossil taxa? Came for the fats and stayed for the interests… I really like echinoderms !!

echinoderms are fucking sick!!! pls be shhhhh about this but i have a spot where you can find some of the most gorgeous early cretaceous-aged sea urchins, spines and porocystis preserved🫣

museum quality shit. i got to handle a collection worth millions that was full of these and it was LIFE CHANGING

but. i am a plant fossil nerd 😭 i collect a lot of petrified wood!!! my fav pieces are from oregon—although they have some gorgeous opalized/silicified stuff, TX rivals it in beauty imo. ppl just don’t polish their shit here..

conifers are my fav!!! i have a few metasequoia fossils (cone, leaves) and i want more 🥺

Coon Creek Formation, Tennessee

The Coon Creek Formation is a Late Cretaceous rock unit in western Tennessee. At the type-locality near Enville, Tennessee, this formation is an internationally-recognized Lagerstätte— which simply means that it is an area of excellent fossil preservation.

📍Location 🗺️

The type-locality, where the formation was described, is located near Enville, Tennessee, in the Coon Creek. Although the naming might sound suspicious (especially given the South’s racist history), this creek was actually named for the numerous raccoons that call the forest home. I’ve attached a picture of some raccoon tracks I found on the banks of the creek!

🪨 Geology ⛏️

This unit was initially a member of the Ripley Formation (Late Cretaceous rock unit that exists as part of the Cretaceous Belt in Mississippi and Alabama). In 1975, geologist Ernest E. Russell raised this unit to formation status.

The dark gray rock (a very fine- to fine-grained sandy marl) pictured above comprises the lower, fossiliferous unit of the Coon Creek Formation. Marls, by definition, are silty-clays/clayey-silts that are rich in calcium carbonate. This marl has a particularly high clay content which, coupled with the regional river drainages pumping sediment into the paleo-Mississippi Embayment, ensured that deceased organisms were buried rapidly.

🦕 Paleontology 🦖

The Coon Creek Formation represents sediment deposition in a shallow marine environment proximal to the shoreline. As such, the fossils found here are those of sea-dwelling organisms, including: mollusks (clams, oysters, cephalopods, sea snails), arthropods (shrimp, lobsters, crabs), echinoderms (urchins), and vertebrates (fish, sharks, turtles, and marine reptiles). Fragmentary dinosaur fossils have been found in the Coon Creek Formation, though they are quite rare.

The state fossil of Tennessee— a clam called Pterotrigonia thoracica— can be found in abundance throughout the creek.

🏕️ The Coon Creek Science Center (CCSC) 🔭

The CCSC is a 240-acre field station owned by the Memphis Pink Palace Museum and operated by the University of Tennessee at Martin. The CCSC also hosts the type-locality for the Coon Creek Formation.

The science center has a museum, field laboratories, bunk facilities, mess hall, weather station, and astronomy observing capabilities. On the third Saturday of each month, they host a Community Day, where people are welcomed into the creek to collect fossils for themselves. Afterwards, the on-site paleontologists will help you to identify your finds and teach you the basics of fossil preparation! I highly recommend this to anyone who wants a real hands-on experience in fossil hunting.

I got to see some really well preserved dinosaur footprints over the weekend! Pics under the cut :3

The prints are from acrocanthosaurus and iguanodon! They date back to around 113 million years ago!!! We also have evidence that there were two iguanodons present, an adult and a juvenile.

Here’s a closer look at one of the iguanodon prints :)

I also got to do a fossil dig and I found a bunch of cool marine fossils! I was lucky enough to find a wonderfully preserved worm tube. I also found some bivalves, foraminifera, gastropods, and a sea urchin.

These are from the Cretaceous when America was split in two by the Western Interior Seaway, leaving Texas and some other states underwater. Texas being underwater is also why we have such great dinosaur footprints!

"Unveiling the Ocean's History: Fossils of Ancient Deep-Sea Creatures Dating Back 104 Million Years"

Researchers have uncovered fossil proof indicating that advanced invertebrates, particularly irregular echinoids, also known as sea urchins, have successfully established a stable presence in the deep sea for a minimum of 104 million years, tracing their origins back to the Cretaceous period. By meticulously studying more than 40,000 spine fragments obtained from sediment samples, the scientific…

[G]rowing up on the Chalk as a child means scrabbling about in chalk pits until you are as white as a ghost, crushing lumps of soft chalk on the road to draw big rude words in a blazing white mess, and the exhilaration of finding Cretaceous fossils such as echinoids, which are extinct sea urchins from around 65 million years ago, locally referred to as ‘shepherd’s crowns.’  From his writing, and especially The Wee Free Men, where chalk features to the fore, I now sense that Sir Terry was very familiar with this geology from an early age.  If it can fur up the workings of a kettle, then it must accumulate in the body somewhere; if not in the blood then encrusted around the human element.  The formation of chalk from ‘the shells of billions and billions of tiny, helpless little sea creatures that died millions of years ago,’ to quote from the aforementioned Tiffany Aching volume, is a stunning realization.  Just look at the white cliffs of Dover to measure for yourself the scale of this sedimentation.

Echinoids, echinoids, echinoids these little fossil urchins litter our beaches and are among some of the most common fossils to be found on our island shores!

They date to the late Cretaceous period, a time when Europe lay beneath an open 300m deep ocean, their little lives once played out on the muddy substrate of the ancient seafloor, and 70 million years later we can still find them all around us!

This is particularly beautifull sand from a place that has marine fossils from the .... hm ... there are some Ammonoidea ... so ... some point or points between the Devonian and he Cretaceous period ...  wait ... that is shelf ... because there are sea urchin stingers, ... and I think one whole tiny little sea urchin ... and I think some coral shards ... that means there should be sea lilies ... but there aren’t any ... at least none that I can see ... so ... might be Cretaceous (they moved to the deep see regions in the Cretaceous period) ... or the ones that lived there where just a lot bigger XD

Turtle Café Is it a bird? Is it a plane? No. It’s the ‘Turtle Café’ ‘Turtle Café’ can be found in the tourist camp ‘Bayanzag’ situated in ‘Gurvansaikhan National Park’, Gobi desert, Mongolia. Is turtle architecture a thing? ‘neon urchin’ say, here’s to more of it. Time for a little bit of history. ‘Bayanzag’ is famous paleontological site within the Gobi ‘Gurvansaikhan National Park’. Many millions years ago (approximately 80 million), in the upper Cretaceous formation, these basins used to be a swamp populated by dinosaurs, old mammals and birds. In the last century an incredible number of well preserved fossils (full skeleton, bones, clutches of dinosaur’s eggs) have been found in this region. The old Chinese-Mongolian dragon mythology is said to have its origin in the discovery of dinosaurs in Gobi. ‘Turtle Café’, Bayanzag, Gurvansaikhan National Park, Gobi desert, Mongolia. #neonurchin #neonurchinblog #dedicatedtothethingswelove #suzyurchin #ollyurchin #art #music #photography #fashion #film #words #pictures #neon #urchin #flamingcliffs #bayanzag #gurvansaikhannationalpark #gobidesert #mongolia #dinosaursbones #dinosaureggs #restaurant #café #architecturalfeat #turtlecafe (at Flaming Cliffs) https://www.instagram.com/p/COsHKi2F3mP/?igshid=1b2dxcgu796ke

Preface to Spring And Ashura by Kenji Miyazawa

The phenomenon called I Is a single blue illumination Of a presupposed organic alternating current lamp (a composite body of each and every transparent spectre) The single illumination Of karma’s alternating current lamp Remains alight without fail Flickering unceasingly, restlessly Together with the sights of the land and all else (the light is preserved…the lamp itself is lost)

These poems are a mental sketch formed faithfully Passage by passage of light and shade Maintained and preserved to this point Brought together in paper and mineral ink From the directions sensed as past For these twenty-two months (the totality flickers in time with me all sensing all that I sense)

People and galaxies and ashura and sea urchins Will think up new ontological proofs as they see them Consuming their cosmic dust…and breathing in salt water and air In the end all of these make up a landscape of the heart I assure you, however, that the scenes recorded here Are scenes recorded solely in their natural state And if this is nihil then it is nothing but nihil And the totality is common in degree to all of us (just as everything forms what is the sum in me so do all parts become the sum of everything)

These words were meant to be transcribed truthfully In the monstrous bright accumulation of time Of the present geological era Yet they have gone ahead and altered their construct and quality In what amounts to a mere point of contrasted light (or alternatively a billion years of ashura) Now it is possible that both the printer and I Have been sharing a certain turn of mind Causing us to sense these unaltered In all probability just as we are aware of our own sense organs And of scenery and of people through feeling And just as what is is but what we sense is common So it is that documents and history…or the Earth’s past Are nothing but what we have become conscious of Along with their divers data (at the root of the karmic qualifications of space-time) For all I know in two thousand years from now An appropriately different geology will be applied With fitting proofs revealed one after another from the past And everyone will surmise that some two thousand years before The blue sky was awash with colorless peacocks And rising scholars will excavate superb fossils From regions glittering with iced nitrogen In the very upper reaches of the atmosphere Or they might just stumble Upon the giant footsteps of translucent man In a stratified plane of Cretaceous sandstone

The proposition that you have before you are without exception Asserted within the confines of a four-dimensional continuum As the nature of the mental state and time in and of themselves
