people will remember:

What is prospecting?

In paleontology, prospecting means carefully scanning and exploring the landscape for fossils exposed at the surface. Several of our active dig sites were first discovered this way by participants, proof that just being observant can lead to real scientific discoveries!

Introducing Xenovenator espinosai, a new troodontid dinosaur with some fascinating cranial anatomy. I had the honour of being approached to create the illustration for this week’s official announcement. (1/3) #SciArt

#Xenovenator is one of the first named dinosaurs of the year! Assigned by Rivera-Sylva et al (2026) to the troodontid lineage, it has oddly thickened frontals - creating a bulbous/domed forehead. Could this be a combat or display adaptation? It's remains from Coahuila, #Mexico date back ~73m years.

Happy #FossilFriday from the West Gold Hill Dinosaur Tracksite in #Colorado! These sauropod footprints are exposed for roughly 100 meters and can be accessed via a hiking trail on public lands! Apart from being a notably long trackway, they are also unique for being at ~2800 meters in elevation

Out in @nature.com today, we shake up the ornithischian family tree. Remember those weird Late Cretaceous iguanodontians, the rhabdodontids? Well they're weird because they aren't iguanodontians. They're ceratopsians. Well, at least some of them are... www.nature.com/articles/s41...
A hidden diversity of ceratopsian dinosaurs in Late Cretaceous Europe - Nature
New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.

Did spinosaurids really survive into the latest Cretaceous? The postprint for our latest work on these incredible dinosaurs is out today, where @neilgostling.bsky.social, @tetzoo.bsky.social and I examine claims of spino persistance beyond the Cenomanian www.ameghiniana.org.ar/index.php/am...

2025 was eventful to say the least... In my world, and why posting Dino Facts has been much less frequent, is my little hatchling arrived! A big shoutout to @adamrl.bsky.social for putting this Rex & chick print for sale so I could hang it in the nursery!

Hopefully 2026 is less hectic for us all

By my count, 46 new species of Mesozoic dinosauromorph (& lagerpetid) taxa this year, which is close to the average for the time period 2003-2025 (the range over which I have been compiling data):

New alvarezsaurian dinosaur Manipulonyx reshetovi: www.zin.ru/journals/tru... As if alvarezsaurid hands couldn't get any weirder, this one preserves several odd, spike-like elements, interpreted as adaptations for gripping eggs. I have thoughts but they'll have to wait... 🧪 (📷Averianov et al.)

Interesting preprint suggesting that recently described fossils from Brazil described as a new ctenochasmatine pterosaur, Bakiribu, preserved within a regurgitalite, instead represent the gill arch apparatus of an actinopterygian fish:

The "caudofemoralis longus" is a muscle that leaves obvious evidence of its existence on the bones of dinosaurs. This muscle that retracted the leg during locomotion was anchored to the thigh bone at the 4th trochanter (see pic, labeled "d" where the bone is deformed by musc stresses) & to the tail.

There were so many big paleo publications made this year, especially in the last few months. First sauropod with gut content, nanotyrannus X2, new hadrosaur mummies, new pterosaur in vomit. You think any more big things will come before the year ends????

Hadrosaurid dinosaurs are generally regarded as “crested” or “non-crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non-crested” hadrosaur is known to ha...

What might be my favourite fossil has been just published by Kiat et al. 2025. Years ago I saw a pic of this Anchiornis specimen in nat geo article and I audibly gasped.preserving not only the feathers but also the original patterns as well. I made this drawing on the spot. Maybe its time to do v2.0

Have learnt from Andrea Cau that French palaeontologist Philippe Taquet died yesterday, aged 85. Taquet published a substantial amount on north African and French #dinosaurs, including Ouranosaurus, spinosaurids, the dromaeosaurid Pyroraptor and much more.
