I’m a high school biology teacher who 3D prints bones/fossils in my free time
Instagram got a flying torso, you all get a headless flying pterosaur. Tupandactylus is almost done! #pterosaur #skeleton #3dprint

The lighting isn’t great due to the weather but I’m too excited to not share this: my #Tupandactylus skeleton articulated fully for the first time! Now to get it into the air… #pterosaur #fossilfriday #skeleton #3dprint

A fun observation I made while working on Tupandactylus: the head, neck, torso, and phalange 1 of digit 4 (the first bone of the wing finger) are all approximately the same length. #Pterosaurs have such weird proportions.

The estimated wingspan of the model from wingtip to wingtip. The spine is articulated and the arms are laying down on the ground and are up next in my plans for this model.
A remeasure showing the unit conversion to Imperial Units. 90” is 7.5 feet.
I spent most of the day working on my Tupandactylus skeleton and can now estimate how wide it’ll be with the wings extended. This will be my largest project yet!

My 3D print of Tupandactylus navigans, GP/2E 9266 Most elements are original, some elements are mirrored, even less was digitally sculpted. This skeleton is currently being painted and articulated by me.
If you see this, post a skeleton

Happy #fossilfriday! Here are some pictures of a #3dprint of an #Arthropleura juvenile! It took over 100 years to describe the head and me 3 only days to track down and print the data. The body print is 300% scale and the head is 1000%.

Plateosaurus. A model sculpted by Nova Studios.
An Ontogeny Series Top: Massospondylus adult Middle: Massospondylus Juvenile Bottom: Mussaurus hatchling or embryo
Nwegvu intloko, a contemporary with Massospondylus and previously identified as a sub-adult Massospondylus. This skull and the juvenile skull from the previous picture are on display at the Royal Ontario Museum as part of an ontogeny series made prior to the recognition of this new genus.
All the Sauropod projects that fit on my shelf. The new skulls are the titanosaur Sarmientosaurus (large skull) and the small skull behind it on the self itself is Eoraptor.
I have the week off from school so I’m taking some time to paint. Today I finished painting every Sauropodomorph in my collection!

The Triassic Cuddle
The skulls of both animals. Thrinaxodon is the top skull, Broomistega is the bottom skull
Happy #fossilfriday! Here is a print from this past summer: The Triassic Cuddle! The Cynodont Thrinaxodon, the Temnospondyl Broomistega, and cast of the burrow Thrinaxodon likely dug. I prepped the burrow digitally to expose the skeletons, removing what would have been the floor of the burrow.

Mantellisaurus left hand as preserved.
A complete left hand with missing bits scaled down and mirrored from the right hand of an Iguanodon.
Happy 200th birthday to Iguanodon! Or should the recognition go to Mantellisaurus since most of the British material now belongs to that genus? Either way, here is a composite left hand of Mantellisaurus I 3D printed. The incomplete hand is original material, the filled in bits are from Iguanodon.

Blocky letters say "Briks with Bask!" on a red background. A Lego alligator peeks in from the bottom (that's Bask the alligator).
Paleontology meets Lego in our new video series Briks with Bask!
In the first episode, Will builds a Lego Geologic Time Scale, complete with critters from throughout Earth history!

I segmented the CT data from this paper and 3D printed the vertebrae, thanks for sharing it!
26.01.2025 01:03 — 👍 2 🔁 0 💬 0 📌 0I’m gonna have to grab it! I really appreciate it when researchers like yourself make the data available! Dearc’s hand in particular is going to be super helpful for my current project of restoring the Tupandactylus described in 2022 as I’m stuck on how to accurately articulate its hand.

For #fossilfriday I have the holotype skull of Dearc sgiathanach! This is the 2nd holotype I 3d printed from MorphoSource. Dearc is a large Scottish Pterosaur whose formal description was published today, congrats to @nataliajagielska.bsky.social et Al. On publishing! doi.org/10.1186/s128...

Dearc and Ceoptera drawing
Dearc skeleton photograph by Greg Funston
Dearc sgiathanach, one of the largest well-preserved pterosaurs from the Jurassic, now fully analysed! The description of this toothy Scottish fella, hot off the press, hit BMC E&E. But what does it tell us about pterosaurs? 🤔

I 3D printed a whole pterosaur! More than some assembly required, this Tupandactylus navigans is arguably going to be the coolest thing I’ve made up to this point. Painting and more processing to come eventually.

A pterosaur pelvis, pteroid, and… phingers? Some lovely progress on #3dprinting the Tupandactylus skeleton!
18.01.2025 14:18 — 👍 1 🔁 0 💬 0 📌 0And even beyond this: my school just found out I do this for a hobby and they want me to write a curriculum proposal for a new class which I exciting that my school admin/department sees the value in 3D printing/photogrammetry

My current project is 3D printing a partially restored skeleton of the pterosaur Tupandactylus navigans specimen known as GP/2E 9266! This skeleton was recovered from a police raid of Santos Harbor, Brazil in 2013 and formally described in 2021. #pterosaur #skeleton #3dprint
12.01.2025 21:48 — 👍 2 🔁 0 💬 0 📌 0Totally fair! I will say that the first 2 sources I mentioned have a ton of free files so it is at least 1 less barrier for when you’re ready to do your own! MorphoSource is free but you have to request access to data a lot of the time, though I’ve had requests denied before
12.01.2025 18:39 — 👍 1 🔁 0 💬 0 📌 0Thank you, and will do! I ised to make TikTok’s around this hobby but stopped once that law got passed in the US 9 months ago. I can’t transfer those videos due to music licensing differences between it and YouTube but I’ll probably start fresh there! And maybe stream a bit of my process too
12.01.2025 17:57 — 👍 1 🔁 0 💬 0 📌 0It’s a mix of most of the above! The T. rex was a model sculpt I paid for, I rendered the Titanosaur skull from CT scan data, and the Stegoceras skull came from a database specializing in 3D meshes of primarily biological specimen. MorphoSource, SketchFab, and Cults3D are my big 3 sources for files
12.01.2025 17:55 — 👍 1 🔁 0 💬 1 📌 0Yep! I use wood filler to fill gaps between larger split pieces and to smooth the print where it interfaced with the supports. Then I’ll paint a primer coat and see if need more filler and add more if needed. If not I’ll continue my painting process with a darker wash followed by a lighter dry brush

Hello! My name is Chris and for fun I like to 3D print life-sized models/replicas of various fossils. Here is about 70% of what I’ve made up to this point over the last 2.5 years or so.
