Spinosaurids are as enigmatic as they are diverse, Suchomimus at perhaps 11 metres was the largest known member of the Baryonychinae, while Irritator at around 6 metres is regarded as the smallest of the Spinosauridae.

Thought I’d get myself a T-shirt printed for DinoCon next month, so people know who I am. Putting my name on it seemed a bit naff, so I did this instead. I think it’s very “me”. 🤷‍♂️
A grey T-shirt, with a simple black print on the front. The print includes one of my pencil sketches of a T. rex, and beneath it a “No AI” logo, along with the words “No to AI-Generated Dinosaurs. Keep Palaeoart Human”

For #valentinesday and #FossilFriday, here's Tyrannosaurus engaging in face biting, a behaviour evidenced from numerous tooth gouges and puncture wounds in their skulls. Among living species, face biting is strongly correlated with the onset of sexual maturity, so this image is love-adjacent, sorta.
Two Tyrannosaurus wrestle by biting one another ON THEIR MOTHERHUBBIN' FACES. They lean towards the right of the image, the further animal trying to wrench its jaws out of the bite of the closer. One foot of each animal is off the ground, and the tail of the closer individual arcs upwards. Dust and debris scatter as they stagger around the clearing. Behind them is a nice, pleasant day with blue skies and shady trees; the sort of place you might picnic if it weren't for the threat of two 8-tonne reptiles trampling you while they settled their differences. The experience is similar to being in some city parks.

Let's celebrate #DarwinDay by reminding ourselves that everyone has moments when they feel worse for wear.

Darwin wrote to Charles Lyell in 1861:
"But I am very poorly today & very stupid & hate everybody & everything."

#Iguanodon was formally named 200 years ago today in 1825. The second dinosaur to be named after Megalosaurus, and one of three genera originally used to define Dinosauria.

Happy 200th birthday #Iguanodon!

Despite being the first dinosaurs to ever be discovered, it was the second dinosaur to be described and named.

This iconic ornithopod was quite wide spread across Europe. It boasts a large thumb spike likely for grasping plant and could be used to defend itself.
Me next to an old “kangaroo” stance Bernissart Iguanodon cast mount at the Sedgwick Museum at Cambridge. A modern Iguanodon on all fours (likely still a facultative quadruped) from better myology and anatomical studies and mass analysis at the Senckenberg Museum in Frankfurt.

Happy 200th Birthday Iguanodon!

Very much a fan of your early-20th century look depicted by Gerhard Heilmann, with prehensile tongue and power-walk
A coloured painting, depicting two Iguanodon in a forested environment. The Iguanodon are bipdel and very scaly, with iguana-like crested heads. One is walking in the foreground in a determined manner, with thumb-spikes outstretched, and in the background one is stretching up to eat leaves from a tree, with a prehensile tongue gripping the branches.

Iguanodon was named 200 years ago today, so here's (AFAIK) the first time it appeared in #paleoart: an 1833 watercolour/pencil study "Reptiles Restored, the Remains of Which Are To Be Found in a Fossil State in Tilgate Forest, Sussex" by George Scharf. That's Iguanodon on the left. #Sciart thread...
Watercolour and pencil sketch showing a Cretaceous landscape as understood in 1833. A lizard-like Iguanodon is shown at left alongside a large palm tree, its tail whirling over rolling hills in the distance. A meandering river bisects the scene, with other animals along its banks. These are, from the top down, a swimming plesiosaur in the stream, a monitor lizard-like Megalosaurus, stork-like birds, the spiky Hylaeosaurus, another swimming plesiosaur, a somewhat dog-like crocodile, and two turtles. The right side of the image shows fern-like plants, reeds and more palm trees.

My poster on the life appearance of Megalosaurus, as presented at SVPCA 2024. A paper on this, and the history of M. reconstructions, is currently in the system and should (hopefully!) be published later this year. Posting this in the interim as a poss. useful #paleoart reference. #Sciart #dinosaur
A text-heavy poster detailing what we might predict about the life appearance of the medium-large predatory dinosaur Megalosaurus. Various reconstructions abound, with a timeline of historic interpretations on the left, the oldest known life reconstruction of Megalosaurus in the top right, and my own reconstructions in the middle and bottom.

We'll be having the online launch for Palaeontology in Public on Tue 18 Feb 18:00-19:30 UK-time

It will feature comments from Mike Benton, Riley Black, Natalia Jagielska and Alison Laurence, & discussion with some of the chapter authors

More info & signup link here: forms.office.com/e/gpWburvZPk
Poster advertising the launch event for Chris Manias (editor), Palaeontology in Public (UCL Press, 2025). It contains the following text: Online Book Launch Tuesday 18 February, 18:00-19:30 (UK Time) on Zoom Chaired by Adrian Currie Responses from Mike Benton, Riley Black, Natalia Jagielska and Alison Laurence And discussion with some of the chapter authors. Register at: https://forms.office.com/e/gpWburvZPk There is also an image of the book cover. This features the text "Palaeontology in Public: Popular Science, Lost Creatures and Deep Time. Edited by Chris Manias." The cover image depicts a large long-necked Sauropod dinosaur, modelled after the famous animation "Gertie the Dinosaur" in a park, with a city skyline in the background. A range of humans are standing around Gertie, pointing at and admiring her. There is also a man in a ringmaster outfit standing on Gertie's shoulder.

So, you want to be a palaeontologist and study prehistoric life, but don't know where to start?

Maybe you worry you're not good enough? That you can't do field work? Or you can't afford it?

Let me take you through different options for making it in the field 👇(🧵)
