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!

#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!

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. 🦕

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 🧵

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.
