Not all fossil bones are giants! This is a humerus from a pocket gopher (Thomomys sp.) from the #Pleistocene deposits at Diamond Valley Lake. @westernsciencecenter collection.

For #FossilFriday I want to share an amazing Ptychodus martini "shell-crusher" shark tooth I found in a gravel bar on a creek in #AustinTX.

It's a bit of a hike to this part of the creek, and when I sat my backpack down to rest for a bit, this gem was beneath the strap of my pack.

This is the largest of the 20+ Ptychodus teeth I've found on this creek, and the best preserved. It eroded out of the Austin Chalk, and is from about 85mya.

Always excited for it to be #FossilFriday! An old friend was recently at the Chicago Field Museum and sent some some pictures of Sue the T-Rex. I have yet to have the pleasure to meet her but do plan to one day, along with Big Al, Black Beauty, and the Fighting Dinosaurs.

Makes me curious, what fossils do any of you want to see in person? Basically, what’s your Fossil Bucket list??

A previously unknown giant herbivore discovered (video)

A new subspecies of grass lizard, which has been named Garumbatitan morellensis, was discovered in Spain.

This new dinosaur has been named Garumbatitan morellensis and was 10 meters high and 25 meters long.

The herbivore was a four-legged herbivore with a long neck and tail, not unlike a brachiosaurus.

An article published in the journal "Nature" reports a study on a trilobite fossil of the species Bohemolichas incola dating back to around 465 million years ago, in the Middle Ordovician period, which reveals the contents of its guts in the last meal that occurred before its death. A team of researchers subjected the fossil in to a sophisticated synchrotron microtomography.

All dinosaurs evolved with tails. Their length was relative to the dinosaur's body, while the thickness, shape, and special features, determined how the dinosaur used it. #Paleontology

Paleontologists are busy in northwestern Alberta after a pipeline crew uncovered a fossil of a dinosaur. The fossil skeleton is of the creature's tail, and experts believe the prehistoric beast may have been up to 10 metres in size. The Canadian Press.

One of the things that makes Baru iylwenpeny so special is that we have a lot of it. There are seven skulls, and dozens of postcranial bones This makes it the single most completely known mekosuchine crocodile in Australia, if not the world (there are apparently a lot of Mekosuchus inexpectatus bones - but little of it is published and I don't think there is a whole skull known).

So let me tell you guys a little about this magnificent new crocodile. The species name is 'iylwenpeny' but is pronounced "eel - OON - bin - yah" which looks about as far from the spelling as it is possible to get. It is an Anmatjerre name (an Arandic language from central Australia) and means "skilled at hunting".

Among the nearly 100 specimens on display is this “elbow-bone” (technically, the olecranon process of the ulna) from the extinct camel Camelops hesternus. It’s from the #Pleistocene of Temecula, and is covered with bite marks from a carnivoran. The images show the #3dprint in the Mobile Museum, and the original specimen @westernsciencecenter.

For #FossilFriday I want to share this Squalicorax kaupi shark tooth I found in a creek bed in #AustinTX. This belonged to a Cretaceous crow shark, and presumably eroded out of the Ozan Formation before I found it among the creek gravels. It's one of about 100 shark teeth I've found in Austin.

For today #FossilFriday I found a photo from the Smithsonian Natural History museum of a Shell Crushing Mosasaurs skull.

I, like probably many people, think of Mosasaurus Marine Reptiles as hunters of other Reptiles and fish. But there are species that have strange Mushroom shaped teeth that speckles in eating hard shelled critters. Really created a unique skull compared to that of the traditional razor sharp teeth.

Hiya Mastodon,

Re- #Introduction time! I'm Ash, a stop motion animator of wildlife and paleontologist.

In the last year I moved from Australia to France and to Mastodon from my ex Twitter handle @aela_wild.

With the move I renamed my business to StudioWild. So far it's a better fit :)

Now that I'm set up, I post about natural history and share my mixed media art. I'm looking forward to getting to know my new landscape and all the weird wild animals and places in between.

If you're inclined, my animations live on YouTube https://www.youtube.com/@studio_wild

One of my wiwaxia for #InverteFest!

This is a handprinted Wiwaxia, a half billion year old soft-bodied animal covered in scales and spines. These animals lived in the early and middle Cambrian period and fossils are found worldwide, including in Canada's Burgess Shale. The animals themselves were only about 5 cm (2") but my linocut prints are much bigger.

The creature that kicked this all off is a massive 13,000 year old bison (bison antiques), and occasionally in the last 15+ years, more of his skeleton has been found

We got super lucky this year, finding a radius ulna and some of his ribs! See in the photos how a bone from 2008 fits perfectly with a 2023 find.

His skeleton is on display at the Woodburn, Oregon museum. #paleontology

Hypothesis. Our ancestors evolved bipedalism as they developed tool use (manipulating objects using the hands). Hard to prove, but, the hypothesis meets the requirements of an adaptation that would, does, increase reproductive outcomes.

Scientists excavating in a Peruvian desert have found the fossilized bones of what they argue may have been the heaviest #animal ever to live: a strange ancient #whale called Perucetus colossus.

Its dense bones balanced the buoyancy of blubber and lungs filled with air—essentially they acted as ballast to let P. colossus whales remain underwater with less effort.
