The new motto of this profile:

Ferwen @ferwen.bsky.social · Aug 17

nobody will remember:
- your salary
- how “busy you were”
- how many hours you worked

people will remember:
- how many dinosaur facts you knew
- if you offered others dinosaur facts
- how you made people feel when you told them a dinosaur fact

Another absolutely spectacular entry in David James Armsby’s incredible “Dinosauria” short film series. This might mark the first time Scutellosaurus has a prominent role in a work of dinosaur media, and it makes for a very memorable debut.

The abelisaurid line of carnivorous #dinosaurs likely had a wide range of skin patterns on their head - as noted and mapped by Delcourt (2018). His conclusion: some areas were likely adapted for social behaviours like intraspecies combat. Increasingly armoured heads seem to be a derived trait.

From Delcourt (2018): Skin structures inferred for abelisaurids. Dorsal surface of the skull of (A) Rugops (MNN IGU1), (C) Carnotaurus (MACN-CH 894) and dorsal surface of the fused nasal of (B) Abelisaurus (MPCA 11908). Scales bar: 5 cm.

For #FossilFriday, it's a *NEW PACHYCEPHALOSAURID*(!), and a project that is very near and dear to my heart. Let's welcome #Brontotholus_harmoni!

Animated Scutellosaurus!! (Also Dilophosaurus, prosauropods, and dimorphodonts, but I think I've seen animations of all those before...)

Tyrannosaurus rex was named 120 years ago today on 4th October, 1905.

I would do things a little differently now, but this drawing is from 2020.

It’s National Public Lands Day!

From hiking Montana’s gorges to uncovering dinosaur bones, our work is only possible thanks to public lands. These places are living classrooms where fossils are studied and science connects people across generations.

Go out and enjoy your local public lands today!

A megaraptoran skeleton! From the end of the Cretaceous!

Excited about the announcement of Joaquinraptor, the top predator down south when tyrannosaurs ruled the north. The Schwarzengger to T. rex's DeVito (at least in the arms category). My thoughts:

www.livescience.com/animals/dino...

Gigantic dinosaur with 'claws like hedge trimmers' found with croc leg still in its jaws in Argentina

Speedy megaraptor Joaquinraptor casali had big arms and claws like hedge trimmers that would have made T. rex's forelimbs look puny.

Sorry for the less frequent posting - I have a little human hatchling due soon!

On that note: When most people think of dinosaur hatchlings, they think of #Maiasaura from the famous "Egg Mountain" locale in Montana. This was one of the first discoveries exhibiting dinosaur social behavior (1979)

Fig. 2 from Horner & Makela, 1979.

I’m a Paleontologist

Here’s the most important tip I can give you:
Pick a favorite dinosaur and learn two facts about it

Why?

Because sooner or later, you’ll meet a child with a dinosaur book (or an obsession)

You’ll ask about their favorite
They’ll tell you why
And then, you’ll share yours

#Weewarrasaurus (illustrated below by PaleoEquii on Wikimedia Commons) was a herbivorous dinosaur from Late Cretaceous #Australia. Interestingly, its only known fossils, consisting of jaw fragments with teeth, were discovered by miners in NSW preserved in opal.

A reconstruction of Weewarrasaurus by PaleoEquii on Wikimedia Commons. Note that this dinosaur is only known from jaw fragments, so this reconstruction may be proven inaccurate if more fossil material is ever found

With great pleasure I would like to introduce you to the first ornithomimosaur from Germany!
The fossils of this charming bugger are from Balve, a locality that preserves early Cretaceous fossils in a Devonian reef that had karstified already back then, giving us: cave dinosaurs

So here's the possibly fun bit... That's a camel. It's real skin on a dead camel that's been out in the sun and partially mummified with the fur peeling off. But at first and even second glance it does look like scaly skin from a reptile.

Just released, this paper has big implications. Ornithomimids (ostrich-like dinos) are well known from North America & Asia, but the deinocheirid subgroup is much more rare & fragmentary. Having one of these sloth-ostriches running around the Judith is a fun idea

Here, we describe a potential deinocheirid ornithomimosaur from the Upper Cretaceous Judith River Formation of Montana, represented by isolated left and right dentaries. Compared with ornithomimids...

For #FossilFriday, we have a fossil from our editor Rodrigo Temp Müller.

Macrocollum itaquii was the first complete dinosaur discovered in Brazil. Measuring about 3.5 meters in length and dating back 225 million years, it is the oldest long-necked sauropodomorph known worldwide 🦕

#Aardonyx is a South African sauropodomorph from the Early #Jurassic. Yates et al (2009) describe this dinosaur as being remarkably robust and recover it one of the closest relatives of the true "long-necks" that was capable of walking on just its hind legs. #FossilFriday #paleontology

From Yates et al: (a) Map of South Africa showing the location of Spion Kop 932. (b,c) Reconstruction of the skull of Aardonyx celestae gen. et sp. nov. in (b) lateral and (c) dorsal views. (d) Reconstruction of the skeleton of Aardonyx celestae gen. et sp. nov. scaled to the size of the smaller individual. (e) Histological sections of bones from Aardonyx celestae gen. et sp. nov. (i) shows a transverse section through a rib. The cortical bone consists of well-vascularized fibro-lamellar bone tissue with distinct lines of arrested growth (arrows) and several secondarily enlarged erosion cavities. (ii) shows a transverse section of a scapula fragment showing the zonal nature of the compacta. (iii) shows a longitudinal section of a scapular fragment with calcified cartilage at the articular edge of the bone (arrowed).

#Silesaurus and its relatives are looking increasingly like they are either the ancestors of the ornithiscian dinosaurs or are verrrry close relatives. These "dinosauriforms" have been recovered in a lot phylogenies lately as at or near the base of the plant-eating branch of the dinosaurs.

A sad #FossilFriday with the news that legendary Mongolian dinosaur paleontologist Rinchen Barsbold passed away yesterday at the age of 90. I'm honored to have shaken his hand and more so to have coauthored with him twice, on Tarbosaurus and on Avimimus. R.I.P. Dr. Barsbold. 🦖

Title and Figures 2 & 3 from our 2011 article on a very young Tarbosaurus: https://doi.org/10.1080/02724634.2011.557116.

Title and Figure 1 from our 2017 article on the skull of Avimimus: https://doi.org/10.1080/02724634.2017.1347177.

I am very interested in this - vertebrae don't get enough attention. Thank you for great figures as well!
