Last week, #Thalassotitan was making news for exemplifying what mosasaurs did best: killing anything & everything that lived alongside them! 🦎🔪

First, let's talk about the new kid on the taxonomic block: Thalassotitan! It belongs to a group of mosasaurs called Prognathodontini, all bruisers with insanely powerful jaws & massive, serrated conical teeth - NOT adaptations for making friends!

Next, there is *abundant* evidence of facial biting among mosasaurs. Several Thalassotitan fossils possess bite marks, but perhaps the best example in any mosasaur is this 0.8m long Tylosaurus skull @FHSU_Paleo that is covered in deep gouges, while also having a broken neck.
Goosebeak or Cuvier’s beaked #whale (#Ziphius cavirostris): described as a fossil in 1823 but realised in 1872 to be the same as beached specimens reported in 1820s but given different names. Ziphius is near-globally distributed (pics: specimens from Bay of Biscay; NOAA) 2/n
Bush dog (Speothos venaticus): named as a fossil in 1839 - which explains Speothos, meaning ‘cave wolf’ - and described alive 1843. The same person, Danish naturalist Peter Wilhelm Lund, described the fossil AND living animals, but ... 3/n (pics Attis; Bonne1978; CC BY-SA 3.0)
A new species of #dinosaur has just dropped and word on the street is that it’s pretty similar to the #TRex
In fact, researchers think this discovery could explain why these beasts evolved to have tiny arms!

In 2012, the almost-complete skeleton of a new kind of #dinosaur was found in the northern Patagonia region of #Argentina.
The dinosaur has been christened #Meraxes gigas. The generic epithet is an ode to a dragon in the #GameOfThrones series.

I've just been looking at Big Sara, the privately owned #Allosaurus skeleton (genuine fossil, not a cast) currently on show at Westquay Shopping Centre, #Southampton. What a spectacular specimen! Here are some thoughts... #dinosaurs #fossils
I've heard some concerns about the displaying of this genuine fossil in a food court. I have no idea how the specimen is faring in terms of pyrite decay and so on but...
... it's not in an environment that will contribute to decay. Indoor spaces like this are, in the UK, not humid, but cool and airy. Big Sara is in a big open space close to a giant window. Moving to anatomy...
I just can't believe we're halfway through the year already. I haven't done much at #TetZoo - just no chance - but here's a quick thread of personal highlights of 2022 so far...
First off, I enjoyed putting together my lookback at the 2001 #DorlingKindersley Encyclopedia of #Dinosaurs & Prehistoric Life, a book I co-authored and helped put together during my formative PhD-focused years tetzoo.com/blog/2022/1/29…

The #Cambrian Explosion marks the first appearance of many animal phyla in the #fossil record, but just how radical was it? I'm starting a new #FossilFriday thread where I post Cambrian fossil representatives of one phylum per week. Join me on this trek across the tree of life
Let's begin with #Annelida. In the #Cambrian these come mainly from deposits of exceptional preservation. Polychaetes and sipunculids, including species with potential affinities to living families, are represented.

In 2004, late anthropologist Mire Morwood discovered #fossils of a tiny species of hominin on Flores, an #Indonesian island.
Named Homo floresiensis & dating back to the late #Pleistocene, this was a contemporary of early modern humans in Southeast Asia.

The diminutive hominin bore a resemblance to the australopithecines and even chimps to some extent.
Considering the kind of attention that #LordOfTheRings garnered in the early 2000s, it was only natural that the fun-sized H. floresiensis be nicknamed after #TheHobbit.

To make it also official via Twitter: my first PhD paper came out! We provide a review on the research history of the temporal skull region in tetrapods and how people discussed the evolution of temporal openings from the 19th century until today.

What really baffled our minds was the high amount of terminology introduced for the temporal morphology. Next to the well known "Synapsida" or "Diapsida", and lesser known "stegokrotaphic", there were also mostly forgotten terms like "Anomapsida" or "pseudomonozygokrotaph".
(2/9)
(2/9)
Also the taxonomic content of some of the taxa named after their temporal openings differed over time. For example, did you know that the original Synapsida also included sauropterygians, turtles, and "cotylosaurs", but no "pelycosaurs"?

What is the @Greenpeace position on #fossil gas ? We know that they are against #nuclear power, but if that had to choose, will they first prefer to phase out of #fossil fuels or #nuclear power ?

Our new #IsleofWight #theropod #dinosaurs - Vectaerovenator (not as scary as it looks: 'vect-air-oh-ven-a-tor') from the Greensand of #Shanklin - was published yesterday in an #OA paper, available here: onlinelibrary.wiley.com/doi/full/10.10… Brief thread on this research...
This dinosaur - so far known from four extremely unusual, anatomically interesting vertebrae (two of them shown here) - was discovered by three different collectors, our work on describing them was led by University of Southampton PhD student @palaeoguy12 ... #FossilFriday
It was obvious from the start that this was (1) a theropod (or predatory dinosaur), (2) a new species and genus, and (3) interesting in being highly pneumatic (that is, it has loads of air-filled cavities and openings: you can see those features in these photos)... #dinosaurs
New Paper: 1st dinosaur from #IsleofEigg! We describe a limb bone, & attribute it to a Middle #Jurassic stegosaur! Thread👇 [1/7] #StEiggosaurus #Fossils #Scotland #dinosaurs #FossilFriday
I discovered the bone on @NatGeo funded #fieldwork in 2017. #IsleofEigg is known for #Jurassic marine reptiles & fish #fossils (found by Hugh Miller & others). It was collected by a team frm @GeosciencesEd & Staffin Dinosaur Museum. #StEiggosaurus [2/7]
The bone was badly eroded, but @MrIchthyosaurus carefully prepared it for the team to study. We combined our expertise in #Mesozoic reptile #anatomy and bone microstructure (#histology), to narrow down the identification. #StEiggosaurus #fossils [3/7]
If you’re interested in the history of #dinosaurs, you’ll know the #GideonMantell story, since it’s covered in every single book on dinosaurs. But some new data has just come to light on key events, follow me for a thread… [art by Diego Barletta].
Supposedly, Mantell – a medical doctor and amateur palaeontologist – obtained some fossil teeth while visiting a patient in Cuckfield, East Sussex. He realised they were from a giant reptile, and named the beast #Iguanodon in 1825… #dinosaurs #fossils
The conventional version of the story is that these initial teeth were found by Gideon’s wife, Mary Ann Mantell, while she was accompanying him on a visit to a patient. The #fossils were observed in gravel piled up for road building...
Last week my first first author paper was published, and also my first plant genus and species description! We described Keraphyton mawsoniae, a new fern-like plant from the Late Devonian of Australia. I wrote a little thread about it for #FossilFriday #Palaeobotany #Paleontology
Our paper is available online #openaccess at peerj.com/articles/9321/ “Keraphyton gen. nov., a new Late Devonian #fern-like plant from Australia” #paleobotany #paleontology #plant #taxonomy (2/17)
The #fossil #plant was first discovered by an amateur geologist on the bank of the Manilla River in Barraba #NewSouthWales… more than 50 years ago #NSW (3/17)

It’s #Croctober, so that means I’ll be featuring croc-relatives using the hashtag #AtoZcrocs. Follow along this month for a deep dive into how weird croc #evolution really got.
A is for Anatosuchus, a notosuchian from the Cretaceous of Niger. It’s name means “duck-crocodile,” for it’s oddly flared snout. #Croctober #AtoZcrocs #fossils

Anatosuchus’ upright limb posture and funky snout might have helped it wade in the shallows and root around for small prey. #Croctober #AtoZcrocs #fossils
