Here the result of the Escuminac Formation #paleostream!
These deposits from the Devonian of Canada offer a glimpse into a coastal fish community with some absolute bangers and historical favorites. But it doesn't come without it challenges.
a scar covered Xiphodracon swims in shallower water above a Solenopora jurassica reef, a large rolling wave sweeps above it Xiphodracon is a type of ichthyosaur (marine reptiles that looked like cetaceans but swam side to side like fish) which had a very long torso and long snout Solenopora jurassica is a type of pink jurassic algae which would've covered large areas of shallow water
my sona and an Ectoconcus lay down and sleep together on a bed, the Ectoconcus yawns Ectoconcus is one of the earliest ungulates we have, it would've appeared like a very genetic mammal with a boxy skull, long tail, and five toed feet with large nails resembling hooves at the tips
a Morganucodon pushes dirt out of the burrow it's currently constructing near the protection of some dried out ferns Morganucodon is a kind of mammaliform (animals that eventually gave rise to mammals) that could've fit into the palm of your hand, unlike mammals, the bones which form our ears are still attached to their jaw bones, meaning their ears werent as sensitive and wouldve been on the lower jaw, most likely without any pinnae present
an Atlascystis sifts through fine sediment for food during low tide using its many tube feet, a shallow depression left in its wake Atlascystis is an ancient kind of echinoderm that—unlike its modern—relatives was bilaterally symmetrical rather than radially symmetrical, all of its tube feet wouldve been at the front of the animal and would've been used for locomotion and food manipulation/foraging, it was only a centimetre long
here's what we sketched during this week's #Paleostream flocking!!!

Four colored-pencil drawings of prehistoric animals, arranged roughly into quadrants on a piece of paper. In the top left is the ichthyosaur Xiphodracon, with a very long and slender snout. In the top right is the generic-mammal-ever Ectoconus, leaping away from whatever ripped the tip of its tail off. In the bottom left is the early mammaliamorph Morganucodon, curled around itself as it sleeps. In the bottom right is the bilaterally-symmetric early echinoderm Atlascystis, drawn life-size at just under 1 cm wide at the front end and around 1 cm in length.
Tonight’s flocking #Paleostream sketches: the ichthyosaur Xiphodracon, the early Paleocene mammal Ectoconus, the mammaliamorph Morganucodon, and the Cambrian echinoderm Atlascystis (drawn life-size). #paleoart #sciart #mesozoic #cenozoic #paleozoic
Result from the Pleistocene Sicily #paleostream!
This piece was a fascinating up and down to construct and to research. While certainly iconic our understanding of these faunas is not complete and misinformation and memes plaster ones way. Center of this piece...

Doodles from last Friday's flocking #paleostream featuring Lotosaurus, Metriacanthosaurus, Pterocetus, and Caelestiventus.
Result of the Wellington Formation #paleostream!
People like to think of the Carboniferous as the time of the giant insects but they actually reached their peak in the early Permian. And here in Kansas we find the largest: Meganeuropsis, which in our case in going after a...
Result from the #paleostream!
Spinosaurus mirabilis, Titanotaria, Hanssuesia and Armenohyrax!
Note that I am very unsure about how to reconstruct the facial structure of Titanotaria, but it's #WorldSealDay!
Many more insects and other critters to add to the edge of this playa lake!

a stylised drawing of a person leaning against a Lotosaurus, both of them are sleeping the person in the image is my sona Lotosaurus is a poorly described pseudosuchian reptile that had no teeth and was most likely herbivorous, it's also known for the sail on its back created from its tall neural spines
a Metriacanthosaurus swims in moderately deep coastal waters, a Thalattosuchus swims over to investigate the larger predator Metriacanthosaurus is a large theropod dinosaur known from few remains, here i've chosen to depict the top part of its body (including its head) above the water out of view as this shows the area we can relatively confidently reconstruct Thalattosuchus is a type of fully marine crocodile with very reduced front limbs, long paddle-like hindlimbs, and a vertical fluke on its tail. the group of pseudosuchians it belongs to preserve highly reduced scales, likely an adaptation for their primarily aquatic lifestyles
a surfacing Pterocetus is illuminated by an artificial light from behind the camera. its rostrum breaks the water's surface first, with its wide head disturbing the incoming water in a smooth wave that washes over and crashes behind it Pterocetus is a beaked whale of uncertain affinity, what we do know is that both species had very wide heads, particularly around the areas where the eyes sat, though this would have been obvious in life, it would not have been as obvious as in the bones due to soft tissue smoothing out the form
a Caelestiventus has landed on a small island of rocks to take a drink at night, an artificial light from behind the camera illuminates it with great contrast Caelestiventus is a kind of dimorphodontid pterosaur, like its relatives, it would've been more terrestrially adapted while still being able to fly. it had a long vaguely oval shaped head with thin and long interlocking teeth at the front, and leaf-shaped cutting teeth at the back

Result from the Sulphur Mountain Formation #paleostream! This formation made it onto the wheel as it is the last refuge of the last eugeneodonts, the group that gave us Helicoprion. Most prominently we have here Fadenia, a late surviving durophagous member of this group...

two Tusciziphius are illuminated by an artificial light during the night, one has albinism while the other is a more normal looking colouration Tusciziphius is an extinct species of basal beaked whale that inhabited various parts of Europe and North America throughout the Miocene and Pliocene. both species are only known from skulls, but the skulls provide a unique morphology in the presence of a raised "keel" on their fused premaxillary bones. this may have been an attachment point for a large melon or used for something else, we still arent sure
a Cyrtograptus floats suspended amongst other plankton. the small colonial organism floats along the current, each of the small zooid's tentacles catching bits of ditritus and other plankton that happen to float by Cyrtograptus is a kind of planktonic marine invertebrate that may seem closer related to cnidarians like siphonophores, but is actually closer related to us and echinoderms as it's a hemichordate. this genus is characterised by its spiral coiling with primary and secondary branches of zooids growing from the outer edge of the whorl
a Callawayia has just surfaced to take a breath, it quickly darts back underwater as to not be ambushed from below Callawayia is an ichthyosaur from Canada with a proportionally longer tail than other icthyosaurs, ichthyosaurs were a group of very successful fully marine reptiles that appeared similar to cetaceans however they swam side to side rather than up and down
during sunrise, a spooked Doryaspis kicks up sand with its tail and cornual plates. it shoots jets of water out of its branchial openings from the force of sucking in water to breathe as it makes its escape Doryaspis is a kind of jawless fish that inhabited the Devonian of Norway, it is well known for its heavily armoured body, long cornual plates that look like wide pectoral fins, and long pseudorostrum. while the use of its pseudorostrum are heavily debated, biomechanical studies of the fish show that it wouldve swam the most efficiently close to the bottom of the water.
