Happy #fossilfriday I’ve spent the last few days cutting down the jacket and airscribing around the orbit and nasal bones of this Pachyrhinosaurus lakustai skull. Big Sam is looking fantastic and has some very interesting features for future study. #dinosaur

Sketch of a dapper 19th Century man in coat & vest pointing with a stick to to the tail of a giant marine reptile skeleton, a cast of Rhomaleosaurus cramptoni, from Ward’s fossil catalogue. Some idiot added meme (impact) text: who wore it better.
Dorky rei-core 21st C. dad in replica vintage Monterey Bay Aquarium shirt gestures toward disassembled plaster cast of of a giant marine reptile skeleton, Rhomaleosaurus cramptoni, purchased from Ward’s collection in the 19th C., rescued from a demolished residence hall basement, at Vanderbilt University Archives storage facility
How it started/ how it’s going.
or,
Who wore it better?

Excited to celebrate Salinas Pueblo Missions NM and their remarkable synapsid fossil tomorrow! Meet me at 11 at the Manzano Mountain Art Council for a talk on your cousins, the synapsids! #fossilfriday 🦖🧪

the type specimen of Massospondylus was also lost in WWII, but somehow it's not as famous as Spinosaurus.

A collection of various fossilized dinosaurs bones still intact in rock at Dinosaur national monument.
Fossils on the incredible wall preserved at Dinosaur national monument for #fossilfriday. I hope i can go back again!
A well worn skull fragment with horn core. The river it was found in runs fast, distorts its channel, and loves to grind up its ancient bones as it tumbles them through glacial gravels and Cretaceous seaway landforms. It often crests multiple times a season—a pattern known as pulse flooding.
A well worn skull fragment with horn core. In the spring of 2019, the river where it was found reached a maximum height of 17.92 feet, with two major crests: 17.92 ft on March 24 and 15.02 ft on April 19—high enough to coax the river's banks into revealing a few buried secrets.
#FossilFriday! 🐂 A revelation for me and my friend: bison material could be found along our small town’s river gravel bars.
This right frontal bone is from a juvenile bison. Other skull and horn‑core material have turned up, but this was the first—and remains the only—juvenile skull we’ve found.
A display from the Field Museum showing plant fossils from Oregon and Washington that appear more similar to those of modern Appalachia than the Northwest.
A mural by Larry Felder showing the John Day Basin in the Eocene Epoch, featuring a thick liana (vine) in front of a lake reflecting dense, tropical rainforest-like vegetation.
A mural by Larry Felder showing the John Day Basin at the boundary of the Eocene and Oligocene Epochs, featuring vegetation in fall color and appearing similar to what you might encounter today in the Appalachians or parts of China.
A display at Seattle's Burke Museum that uses plant fossils from around the Northwest to track changing climate during the Eocene, Oligocene, and Miocene Epochs.
Spring has sprung in the Great Northwest this #FossilFriday! With leaves starting to bud it's worth reflecting on our region's incredible plant fossil record and the story it tells of deep time environmental change (Photos from the Field Museum, John Day Fossil Beds, and @burkemuseum.bsky.social).
Continuing with the Early Cretaceous seas of Colombia, the ecosystem's top predator: Monquirasaurus boyacensis, "El Fósil". One of the largest and most complete pliosaurs known, a separate museum had been built around this specimen, leaving it exposed but in situ #FossilFriday
UMMP specimen representing the oldest known larval crinoid arrives in time for #FossilFriday! www.cambridge.org/core/journal...
I may have painted another crinoid mug.
Thanks for the inspiration @kiabugboy.bsky.social for your Dorycrinus.
It will get fired and I'll get it back in a week.

Some sabertooth fun for #FossilFriday! A colleague recently asked me what parts of a Smilodon skull that we published on (bit.ly/4dfOInK) were real. CT is the easiest way to detect restoration. Here, the right canine (saber), a carnassial crown, & all lower incisors needed to be restored. ⚔️🦷🐱

Four encrusted subfossil shells from the SE Brazilian Bight, in interior view. Clockwise from upper left: 1. The rhynchonelliform (articulate) brachiopod Bouchardia rosea dorsal (brachial) valve, with the brachidium broken off and worn as is typical. A large coiled serpulid tube occupies the right side. 2. Bouchardia rosea ventral (pedicle) valve, fragmented along a plane of weakness induced by the endoskeletal boring Caulostrepsis, produced by the kleptoparasitic polychaete Polydora. The interior is encrusted by anomiid bivalves, spirorbids and a serpulid. 3. Bouchardia rosea ventral (pedicle) valve, with mutually overlapping encrusters: a colony of cheilostome bryozoans overgrows a meandering serpulid that turns to overgrow the bryozoans and its own tube. Many smaller serpulids are also present. 4. The bivalve Macoma, pierced by a naticid gastropod drill hole and colonized by cheilostome bryozoans.
For #FossilFriday and in recognition of my PhD advisor Michał Kowalewski joining the AAAS Fellows, a throwback to our work with Marcello Simões and others comparing the skeletobionts (encrusters and boring organisms) that made their home on the brachiopods and bivalves of the SE Brazilian Bight. ⚒️🧪🦪

A closer picture showing the plates of the crinoid calyx. You can see how worn this specimen is from tumbling.
#FossilFriday
This is my smallest crinoid calyx.
It's about 2 mm wide. I found it on my hands and knees in the Devonian Silica Shale of Ohio. It's a bit weathered, but is likely Arthroacantha.
I'm lucky to have access to an SEM at my office.

A special #fossilfriday, as we were visited by several of our illustrious Univ of Edinburgh paleontology alums!
Paige dePolo, Kim Kean, some scrawny balding guy in a flamboyant purple shirt, Sarah Shelley, @davfoff.bsky.social
What great students we've had & long may it continue!
It's always solar windy in space, so solar sails is the way to go.
And plans now finalized for the much anticipated third nacelle.
There's no stopping the time travelers now! (except simple physics & commonsense).

Riguetti et al, 2022. Figure 4 - known elements of Jakapil in white show it is known almost entirely from a lower jaw, a scapula, a few vertebrae, osteoderms, and various fragments of rib/leg/hip/upper-jaw/vertebrae/etc.
Happy #FossilFriday from the enigma that is #Jakapil. It seems to be a ~1 meter long remnant of a very early branch of the armoured dinosaur lineage (containing stegosaurs and ankylosaurs), but many of its features are more similar to other herbivorous dino families.
What on Earth was this thing?

For #fossilfriday, NHMUK PV OR 3775 - the Hylaeosaurus holotype!
Found in 1832 in a quarry in Tilgate Forest, W Sussex, after being gunpowderexploded (new term we’re trying out) into many pieces
One can only speculate as to how complete the specimen may have been with a luckier gunpowderexplosion
