This weeks #Lego #FossilFriday is #Plesiobalaenoptera

In 2010, Michelangelo Bisconti named a newly discovered fossil rorqual (the largest group of baleen whales), Plesiobalaenoptera quarantellii.

The fossils were found in sediments of the Stirone River in northern Italy.

Plesiobalaenoptera has a postcoronoid fossa, or hole in the dentary bone of the lower jaw, which would have made ram feeding difficult to perform.

For #FossilFriday, we have a fossil from our editor Ana Paula Carignano.

This fossil is UNC-PMIC 71 (Neuquenocypris calfucurensis), a right valve of the Upper Cretaceous ostracod from Patagonia. It inhabited lacustrine paleoenvironments & is a common component of the Upper Cretaceous continental assemblages of Patagonia 🐚

My 25 years of palaeoart chronology...

In 2024 I designed the Ice Age Giants coin series, for the The Royal Mint and the Natural History Museum, London. One of the coins featured the steppe mammoth, it was a time to reflect on how long I'd been drawing very dead things!

New blog post!

My friend Eric was skeptical when I told him I was writing posts about ribs. But he loves food, so I’m starting each rib post with a rib dinner from restaurants near the #museum.

This week, we look at the shape of #ribs which turns out to be pretty critical to staying alive.

Life...From a Certain Point of View · Rib connectionsMy friend Eric loves a good meal, so to encourage him to read the posts and recognize how awesome ribs are, I'll be starting each post on rib anatomy with an example of ribs from restaurants near the museum!

🐂 Happy #FossilFriday! 🐴🐘🦥🐪 These bison teeth are survivors. This photo was taken at the bottom of Lake Bronson, Minnesota, which has been drawn down as part of the ongoing dam replacement project. I had the opportunity to participate in a archaeological survey there last Saturday.

The teeth spent nearly 90 years submerged beneath the lake, and an estimated 250 to several thousand years on the landscape before the reservoir’s creation.

This week for #Fossilfriday we have another #Guess that #Lego #Fossil.

This one I would rate as medium. This fossil is known from Italy.

Reminder: hide your answer behind a content warning. This will allow others to guess without a hint. I will post the answer tomorrow (and to anyone who guesses correctly).

This weeks #Lego #FossilFriday is #Wintonotitan

In 1974, Keith Watts found a left shoulder blade, much of the forelimbs, a number of back, hip, and tail vertebrae, part of the right hip, ribs, chevrons, and unidentifiable fragments.

These fossils were given the name Austrosaurus sp, Austrosaurus being the only named sauropod from Australia at the time.

In 2009, Hocknull et al. found these fossils differed enough from Austrosaurus to give them a new name, Wintonotitan wattsi.

Great collaboration with @etschopp (FU Berlin), Andre Saleiro (University NOVA, Lisbon) & partners from LIB Hamburg! Niche partitioning in 3 Jurassic sauropod faunas revealed using dental microwear texture analysis.
We find hints of migratory behaviour for camarasaurids, and a distinct habitat effect for sauropods from Tendaguru - likely due to sand from a nearby desert that settled on forage plants.
