During the early 1990s, John Blashford-Snell, Rula Lenska and other travelled to Nepal to find and photograph the giant #elephants Raja Gaj and Kansha. They succeeded, and got great images of both animals. They later wrote a book about their adventures... 1/n
The twin-domed skulls and convex trunk bases of these animals - Raja Gaj in particular - led to suggestions (albeit only in talks and popular articles) that they were 'living mammoths' or 'living stegodonts'. I asked Blashford-Snell a few times where these ideas came from... 2/n
They were the result of confusion. The Nepalese giants had been compared by some elephant experts to Elephas hysudricus, an Asian #Pleistocene fossil #elephant with very prominent cranial doming. No deliberate reference to mammoths OR stegodonts! 3/n
[Images above by Margaret Flinsch and Paulus Edward Pieris Deraniyagala] While Raja Gaj might look a bit like the extinct E. hysudricus, the similarity is superficial. Old bull Asian #elephants can grow massive twinned domes: look at this animal at Hagenbeck Zoo...
DNA from the Nepalese #elephants confirmed that they're part of Elephas maximus, albeit a bottlenecked population. The story of 'the living stegodonts that weren't' is covered here at #TetZoo... tetzoo.com/blog/2022/8/24…

A brief thread on #mammals that are are alive today but were first described as #fossils.... 1/n
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)
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 was lead scientific consultant on #PrehistoricPlanet and was extensively involved in our many decisions, all of which were science-led or scientifically informed. I was, of course, merely one among many in a HUGE team that involved hundreds of very talented people!
Ep 5 focuses on the #dinosaurs and #pterosaurs that lived in forests during the Maastrichtian (the final part of the Late #Cretaceous). The Maastrichtian world was heavily forested, with temperate, subtropical & tropical woodland covering around 78% of the land surface…
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…
Welcome to another thread on the science behind the new @AppleTVPlus@bbcstudios series #PrehistoricPlanet, specifically EP 4: ICE WORLDS. This thread will work best if you read the tweets as you watch the episode in real time – do this if you can…
I was lead scientific consultant on #PrehistoricPlanet, and it was a great privilege to work with so MANY excellent and talented people ... such an amazing team! Here we go...
Ice Worlds focuses on the #dinosaurs of the far north and south of the Maastrichtian (very latest #Cretaceous) world, places where conditions were cool or cold – especially in winter, of course – and where the flora and animals were adapted for seasonal darkness and cold…
Freshwater kicks off in north-east Asia (a location consistent with the geology, climate and animals we show) with a spectacular waterfall connected to canyons. Juvenile #pterosaurs - they're young #azhdarchids - have gathered here to roost... #PrehistoricPlanet
We know essentially nothing of the roosting or resting habits of #azhdarchids but see it as likely that they would have gathered in numbers (fossil evidence does show that they were social) in places that predators couldn't easily get to. Hat-tip to discussion with @MarkWitton ..
