@depthsofwikipedia.bsky.socialReposted by @ichnologist.bsky.socialfour years ago I posted this image of paleontologist Jan Smit looking at rocks and his son-in-law replied with something even better

@ichnologist.bsky.socialSo glad to hear you're going! Wish I could be there, both for the conference & Denver-area field trips, but saving all of my pennies & time for the IPC meeting in Cape Town. Have fun there learning & meeting friends old & new!
@ichnologist.bsky.socialHurricane Isaias's effects here in the metro Atlanta GA haven't been as dramatic as expected, with high rainfall & gusting winds late last night, some storm damage, & power outages. Looks like we were lucky this time, now hoping the best for people who were & are in its direct path.
@ichnologist.bsky.socialFor #Caturday, appreciating our oldest cat Tao (pronounced TAY-o because we're in Georgia) for his love of life, which includes his human servants. He's wearing a harness because he's leash-trained, allowing us to take him on walks in mornings & evenings.

@friel.bsky.socialReposted by @ichnologist.bsky.socialNeil Landman, Curator Emeritus at the American Museum of Natural History, reflects on his journey into paleontology, the aesthetic beauty and biology of #ammonites, and his groundbreaking research on post-impact survival near the Cretaceous-Paleogene (K-Pg) mass extinction boundary.
@minouette.bsky.socialReposted by @ichnologist.bsky.socialOctober 9 is Nautilus Night, part of the International Cephalopod Awareness Days. The nautilus is a very unusual looking creature; a cephalopod like the squid or octopus, which grows its own shell. They are known as “living fossils,” having survived relatively unchanged for millions of years. 🧪🐡🐙
@ichnologist.bsky.socialScience storytelling FTW! Last night's Atlanta @storycollider.bsky.social event was fun & meaningful. I started us off with a tale about not finding/finding dinosaur tracks in Australia, followed by 4 folks with personal stories related to science. Thanks to our coaches, Meisa & Emma! 🧪 #scicomm
@ichnologist.bsky.socialMy deepest and most sincere gratitude to @theonion.com for creating this story just for me.
@susieoftraken.bsky.socialReposted by @ichnologist.bsky.socialA big thumbs-up for Iguanodon this #FossilFriday 👍

@tweetisaurus.bsky.socialReposted by @ichnologist.bsky.socialFossil taxa are sometimes considered island weirdos without any actual evidence that island effects were important in their evolution. So we wrote a paper on how we could do actual island biogeography in deep time. If you want a copy but can't access it, email me: www.nature.com/articles/s44...
@ichnologist.bsky.socialWow, huge congrats on your new position, Morrigan! Looking forward to learning all about your & colleagues' future contributions to our understanding of Ediacaran community ecology.
@cambriancam.bsky.socialReposted by @ichnologist.bsky.socialWelcome back to #fossilfirday here is a 3D print of a hadrosaur tooth next to a photo of the original specimen that was collected in the Upper Cretaceous (Late Santonian) Eutaw Formation in Green County, Alabama. The tooth was collected in July of 2025 by @friel.bsky.social.
@dragonsofwales.bsky.socialReposted by @ichnologist.bsky.socialI couldn’t let the announcement of a new Tyrannosaurid pass without illustrating it. So here’s my take on the new kid on the block: Tromerosaurus solumons.

@extinctmonsters.bsky.socialReposted by @ichnologist.bsky.socialIn 2019, NMNH debuted new casts of the Stegosaurus and Ceratosaurus skeletons originally collected by Marsh’s teams. Ceratosaurus was casted and assembled in-house, but Stegosaurus was made by RCI. Getting them to fight took great care, and some cardboard stand-ins. #FossilFriday
@jdpardo.bsky.socialReposted by @ichnologist.bsky.socialI suppose it's #fossilfriday so here's the skull of the Permian coelacanth Spermatodus from Texas, courtesy of the AMNH.
