When the Earth Was Green: Plants, Animals, and Evolution's Greatest Romance Plants, Animals, and Evolution's Greatest Romance

Love veggiesaurs? Check out When the Earth Was Green. I wrote an entire chapter about how some dinosaurs, like my beloved “Brontosaurus,” were shaped by how they grazed on greens. 🌱

Hey, paleo nerds! Rocks rock!

In episode #84, Ray and Dave go rock 🪨 hunting through the eons with Marcia Bjornerud, a structural geologist, author, and Professor of Geosciences at Lawrence University, Wi.

Slide show title screen reading "Early Apes in Context: the Ecology, Chronology, and Phylogeny of Eastern Africa's Early Miocene Hominids by Kieran P. McNulty of the University of Minnesota"

I was part of a group from @dallaspaleosociety.bsky.social invited to a fabulous lecture at SMU by @mcnultylab.bsky.social

We have our monthly meeting next Wednesday, "Dinosaurs Under Foot; The Early Cretaceous Borborema - Cameroon Dinosaur Dispersal Corridor” www.dallaspaleo.org Meeting is both in person and on Zoom.

De-extinction is the “let’s colonize Mars” for Biologists. Instead of working to fix & be sustainable, its a frat boy mentality that we can just trash it all and science will undo it. We don’t need to change our behaviors because we can control Z it

This company is in our city and causing a stir amongst our board of directors. What side would you be on in this situation?

Wing bones

Appendicular elements

Proximal articulation of a wing

Working on a new gigantic task. Describing over 300 well-preserved, diverse pterosaur bones from a niche Late Jurassic locality. An independent project led by me and an army of eager local fossil collectors and preparators. 🤫 Look out for it hitting the press later this year!

Day after #FossilFriday The new updated "Glossary of fossil tetrapod tracks" is available open source! Sure to be the go to reference on fossil tracks for decades to come. palaeo-electronica.org/content/pdfs... @utahpaleo-ufop.bsky.social @ichnologist.bsky.social

Some interesting evidence of pathologies in dicynodonts. Possible causes include post-trauma cysts, parasites, muscular avulsions, osteomyelitis, and fungal disease.

Giant short-faced bears were the largest carnivores of the Pleistocene in North America and are subsequently well known in science. Highly studied, small & large forms have been recognised as subspecies, but some researchers have suggested this may be sexual dimorphism! A 🧵(1/3) 🌍🧪🐻

That's so cool.

Adventures In Science At The Icy ‘Ends Of The Earth’ A new book explores how one biologist’s work at the North and South Poles changed the way he sees the world and our place in it.

A new book illustrates the wonders of Antarctica and the Arctic—and the lengths scientists go to to study them before it’s too late.

Author dr. @neilshubin.bsky.social joins us to talk about “Ends of the Earth” and science at the poles.

Tonight's meeting is on Zoom! Come see what fossils our members have found that have them stumped. "Stump the Society" night. dallaspaleo.org

Happy #MosasaurMonday from the Pit of Despair (end stage PhD work), here's an appropriate lizard: Tylosaurus "Heath" on display at the Perot Museum in Dallas.

Does "everything's bigger in Texas" apply to its mosasaurs? I've got a few upcoming public talks addressing just that...& more. Stay tuned!

Happy International Day of Women and Girls in Science - from me and my lab! 🤩

The discipline of Molecular Paleobiology has been pioneered by women scientists - and I am so proud to be part of it and train the next generation of brilliant minds! 💚

Exciting news for aspiring fossil preparators! Applications are now open for our Fossil Preparation Internship—a unique opportunity to gain hands-on experience working with real fossils in a professional lab setting.

Paleontologist and author @neilshubin.bsky.social has been on multiple expeditions to the Arctic and Antarctica.

Now Shubin is out with a new book called that celebrates the incredible variety of scientific research and discovery in these extreme environments.

This year marks the 120th anniversary of Dippy the #Diplodocus, one of the most iconic dinosaur skeletons in the world. With over a century on display and replicas in cities like Paris, Berlin, Buenos Aires, and Moscow, Dippy has had a massive influence on the public's perception of #dinosaurs.

Digital painting of a gar fish in lateral view on a white background. Gar are characterized in part by a long body, long and toothy snout, and somewhat rectangular scales. The scales are shiny bronze colored, while its fins are grey-blue with brown splotches.

Digital painting of a bowfin fish in lateral view on white background. It is a desaturated olive green in coloration, with long splotches.

Digital illustration of the extinct guitarfish Myledaphus in dorsal view on white background. Its coloration is sandy-tan with light powder-blue splotches.

Since @solomonrdavid.bsky.social just followed me, here's some old #paleoart of fish including Atractosteus (gar), Melvius (bowfin) & Myledaphus (guitarfish). These were commissioned for the now award-winning Cretaceous Creatures project

Dinosaur fossils were destroyed in WWII. Now, photos reveal they were a new species Bones of the massive 32-foot-long predator were found in 1914, researchers said.

Not reproduceable, not verifiable, and yet it gets a name and privately held specimens, less problematic than this, get noses turned up at them.

Wahoo!

A little while ago Phil said he was coming by so I got to drag him to ogle some semi secret dinosaur bones near my house

They were a little spicy, but hilariously the hottest fossils we later found at the museum were some stupid Xiphactinus bones

26,000-year-old 'Ice Age' fox found in Utah cave A team of Utah scientists and cavers have recovered a nearly complete skeleton of a 26,000-year-old red fox deep in a cave in Utah’s Uinta Mountains. It is the most complete skeleton of an Ic…

2024 truly wad the year of the Megalosaur. Not only did we celebrate 200 years since the first scientifically described dinosaur, the megalosaurus, was announced but our team along with researchers from @unibirmingham.bsky.social uncovered megalosaur and sauropod trackways in Oxfordshire!
