Prehistoricpencil - Prehistoric Pencil - Tumblr Blog

Brought home a betta for my planted 29 gallon, I'm so happy to see how much better he looks after just a month!

I visited some public farms to get footage for a class project about chicken physiology. I feel like tumblr might appreciate this image as much as I do.

Purgatorius and Tyrannosaurus by Bush Viper 165.

More practice with the charcoal and pencil brushes - I’ve had a cryolophosaurus as my icon for literally years, so I think it’s well past time I actually drew one! I’m really proud of the detailing on the head.

I was messing around with the charcoal and pencil brushes on procreate and I got a little carried away, so have some dinosaur portraits!

Paleopathology is such a cool field! One of my favorite examples is Dolly, a sauropod who had a respiratory infection severe enough to cause lesions on some of its vertebrae.

The pattern of the lesions is super interesting, and a really neat example of the similarities between sauropod and bird respiratory systems!

Do we have any records of fossil dinosaurs afflicted with illnesses? I guess fossils wouldn't really make it easy to preserve dinos that died from proto-flu, but what about stuff like cancers or malformations?

We do actually! Paleopathology is a whole field and there are tons of specimens that showcase signs of illnesses and injuries! It's really cool actually. there are so many examples that I can't even find the one I wanted to share as a prime one (it was an ornithopod that had a whole cancer study done, can't find it anywhere)

but infections were common and there's tons of studies about the signs of those in fossils as well!

and before you say any of these aren't scary: trust me, I have receipts

Just a reminder my blog is trans inclusive. It’s bi inclusive. It is pan inclusive. It is intersex inclusive. It is ace/asexual inclusive. It is aro/aromantic inclusive. It is queer inclusive.

I don’t support terfs or exclusionists.

If you came here looking for an ally in your bigotry you came to the wrong blog. Go away. You are not welcome here.

! PREHISTORIC PLANET SEASON 2 SPOILERS !

I adored the visuals from the thermal imaging scene so much!

New paper supporting lipped theropods was just released!

They looked at the wear patterns on the enamel of a crocodile tooth and a daspletosaurus, as well as the skull length/tooth height relationship for multiple theropods and monitor lizards.

The crocodile tooth had more wear on its exposed side, while the daspletosaurus tooth had similar enamel thickness on both sides, indicating that they were likely covered by soft tissue, which keeps enamel moist and resistant to wear. They also found that theropods did not have a larger relative tooth size than monitor lizards do - the largest teeth belonged to the crocodile monitor, which has extensive soft tissue covering its teeth. This means that even Tyrannosaurus could plausibly have had their teeth completely covered by lips despite their size.

That’s no moon.

I apologize for the lack of streams recently! Starting Ochem + Physics + a new job at the same time might not have been my finest plan. I'm finally getting some sense of a regular schedule, so hopefully, weekend nights will be free enough for me to stream again!

This painting was done completely on stream! I had a blast chatting with people while working on it.

Had a blast working on Larry the velociraptor on stream tonight! Now that he’s ready for fur and feathers, I did some very rough concept sketches for some color ideas. Please let me know which ones you like best or suggest your own!

Was a bit unsure about tumblr live, but I tried streaming art today and I had a blast! I am definitely going to be doing this again, thank you to everyone who tuned in and chatted with me!

Studying evolution is awesome until you have to generate your own phylogenies.

These were some of my more popular Dinovembers from Instagram and the bird app.

Heres some more that didn’t fit in the first post. Genus in the alt text same as before. 

A note to new palaeontology and palaeoart folks coming to tumblr from twitter!

We of the palaeo tumblr community have been using #palaeoblr (with an “ae”, originally to distinguish us from paleo diet blogs that used #paleoblr) as a community tag for quite a few years now, so I’d encourage anyone new to palaeo posting to put #palaeoblr in your tags if you want!

It’s awesome to have you guys here, I hope you enjoy it!

Here's a Mamenchisaurus what I painted.

Unreferenced Tyrannosaurus from my sketchbook!

I love Blue Rhino Studio! I got to see that quetzalcoatlus sculpture in person at the Field Museum in Chicago, I have a picture with it that's basically identical to the first image lol.
