Mamdani announces a new executive order protecting New Yorkers from "abusive immigration enforcement," including requiring ICE to have a judicial warrant to enter NYC property

Spiny little friend. A quick doodle of Haolong dongi, a newly described ornithopod from China with... spikes. Numerous sharp spines grew from the animal's neck and back, seemingly different from all other known dinosaur integuments. Definitely wasn't on my bingo card for 2026 dinosaur finds!

I'd watch a muppet show movie where the muppets infiltrate an academic conference.

#FossilFriday: The Pacific mastodon, Mammut pacificus, known from California and Idaho. This species was described in 2019. This is the second of two species of Mammut from North America, the other being Mammut americanum.

my 10 yr old nephew found this 11myo Gomphothere molar while hiking in Red Rock state park, calif many years ago. We took photos--then turned it over to park staff. They told my nephew that it was sent to the Natural History museum of L.A. with his name as discover. He was so proud! #fossilfriday

It is not often that I make a 2 #FossilFriday posts but, I will make an exception. This is the skeleton of the fish Xiphactinus audax. It was found by a friend looking fossils in the Late Cretaceous (Santonian) Smokey Hill Chalk in Kansas. You think you afraid of the ocean now? You've seen nothing!

For #FossilFriday, we present Paulina Mühlmann. 🇦🇷 In 1935, she conducted the first geological field campaign by a woman at the University of Buenos Aires. She later became Chief of the Petrographic Lab at YPF, collecting key Paleozoic fossils. 🦕 #Geology #WomenInScience #Paleontology

Since it's #haolong day and #fossilfriday here's some #iguanodontian specimens from Liaoning, spanning from 40 cm to over 8 m, many preserved with soft tissue.

This is not the case for the spikes of Haolong. The spikes consist of layered cells, including a stratum corneum, stratum spinosum etc, with keratinocytes and visible nuclei. In other words, the spikes were living skin

happy #FossilFriday. It is very early in the year and I already have a favorite paper with the newly described Haolong. HOWEVER, this is *not* a feathered dinosaur! The structures on Haolong are very different from filaments. A 🧵

Huang, J., Wu, W., Mao, L. et al. Cellular-level preservation of cutaneous spikes in an Early Cretaceous iguanodontian dinosaur. Nat Ecol Evol (2026). doi.org/10.1038/s415...

The tail, similar to the Middle Jurassic Kulindadromeus, is covered in overlapping large scales, diminishing in size moving towards the end of the tail.

As the name suggest, this new dinosaur species exhibits new integumentary structures never seen before in these dinosaurs, a wide array of small, medium and -relatively- large spikes on the body except of the tail.

Maybe a bit late for web timing, but ehy, NEW PAPER ON #fossilfriday!!! I am proud to present you Haolong dongi gen. nov. sp. nov., a new hadrosauroid from the Early Cretaceous of China! The specimen, almost complete, is a juvenile iguanodontian from the Yixian Formation of the Barremian (125 Mya).

In light of today’s palaeo news, and whilst not claiming to be a visionary genius or anything (that’s for history to judge… 😉) I’m just gonna drop my illustration of a quilled and spiky iguanodon from back in 2021. Sometimes you don’t need to be good. Just lucky. www.nature.com/articles/s41...

A bit more refining on this woolly friend! Blender hair is tricky.

The first paper of my PhD thesis, and first solo authored paper is out today! It you like dinosaur footprints or history, this is for you! Open access via this link- www.sciencedirect.com/science/arti...

For #FossilFriday, exquisitely preserved insect burrows (probably beetles) with backfill structure preserved as bas relief on a sandstone surface, from the Early Cretaceous (~130 mya) Botucatu Formation of Brazil. Specimen on display in the Mário Tolentino Museum of Science, São Carlos, Brazil. 🧪🪲🪨⚒️

Happy #FossilFriday! Check out some exciting research that came out last year about tracksites in Chile, made possible in part by a grant from the Jurassic Foundation. ⁣ Congratulations to the authors! DOI doi.org/10.1186/s133...

Reposting this old photo for #FossilFriday: what you are looking at is a fragment of Callixylon wood from the Late Devonian, about 360 million years ago, seen under the microscope. The elongated structures are the conducting cells & there's a hair on the right for scale. 🔬🌿⛏️ #paleobotany

#fossilfriday New fossil art - watercolor/gouache illustration of the earbone (bulla) of Herpetocetus bramblei from the latest Miocene Purisima Formation, Santa Cruz, CA. This bulla is associated with a partial skull (UCMP 219111) which I discovered in 2007. 3x5", ~4 hours.

These turtles filled a wide variety of niches, including fish eating suction feeders, shell crushing durophages and seagrass grazers. Marocokatognathus adds to this diversity with a very long, narrow, curved beak lower jaw unlike any other known sea turtle

The early Cenozoic was a very important time for the evolution of marine turtles. The Paleocene and Eocene of the Oled Abdoun basin of Morocco preserve a high diversity of coastal marine turtles, including early relatives of modern sea turtles, leatherback sea turtles and marine sidenecked turtles

#Cenozoicrewind2025 Meet Marocokatognathus jimenezi! #paleoart #vectorart #sciart #fossilfriday

I don't think I've shared this in a while, so here are some Middle Jurassic British pterosaurs for y'all! #FossilFriday #paleoart #paleontology #Jurassic #sciart

I spent this #FossilFriday at Wadi al Hitan in Egypt, a UNESCO World Heritage Site where early whales like this Basilosaurus are hard to miss as they weather out of the Eocene Birket Qarun Formation. (Wadi al Hitan translates as "Valley of the Whales.")

In the field it wasn't very promising, and there was no body attached to it, like a homeless headman.

Happy #FossilFriday from this stupid Xiphactinus that I found last April! She is fresh out od prep and just as ugly as I imagined she would be.

A few people asked for scale on this fossil. It's about 2.5 cm or an inch long. #FossilFriday

For #FossilFriday just to show that #IsleofWight is so much more than dinosaurs a mammal jaw with roots exposed from the Oligocene some 34 million years ago. From an anthracothere a distant relation of the modern hippopotamus.

These alien looking animals, despite their plant-like looks, are actually close relatives of starfish, sea urchins and even sea cucumbers! Find out more on this odd find here and be sure to check it out before the end of the month: charmouth.org/chcc/fotmfeb... (2/2)

February's fossil of the month is now on display. Found by one of our wardens during a lunchbreak wander, this slab of limestone was hiding a mass of 200-million-year old crinoid heads and tendrils all entwined and laying over each other! #FossilFriday (1/2)

The bulky herbivore, Barylambda faberi, a pantodont from the Paleocene. #FossilFriday ⚒️🧪
