Dystopian future in which taxonomy and anatomical description have been completely abandoned and palaeontology is just thoughtlessly feeding AI drawings of fossils into the next big data set

I wonder if this isn't also an inevitable outcome of the "taxonomy and morphology are important only if they support other research, so let's just speed it up as much as possible so that we can do the 'real' science."

Hot Take for #FossilFriday - the quest to make paleontology "useful" and "relevant" and "high impact" has backfired spectacularly. A hypothetical "Big Data Approaches to Deep Time Ecosystem Services" almost always end up largely disconnected from actual fossils. (thread) <1/n>

That's fair, I guess my experience is visiting collections in countries that are at the complete opposite end of the spectrum to the UK. There is obviously a lot of middle ground!

Jack Lovegrove @jackl0vegr0ve.bsky.social · 11/08/2026
I think part of the reason people are talking at cross purposes about this, is that this issue doesn't just impact UK specimens which are exported. A lot of UK specimens which remain in the UK are also unavailable for study due to weaknesses in our geoheritage laws

Jack Lovegrove @jackl0vegr0ve.bsky.social · 11/08/2026
Tangentially related to the arguments about UK geoheritage, there are several UK museums which have specimens on display which are either entirely or partially unavailable for study because they are privately owned. This situation just doesn't exist in countries with stricter geoheritage laws.

Jack Lovegrove @jackl0vegr0ve.bsky.social · 09/08/2026
This criticism is wild to me because, to me at least, a museum IS it's collection. All of the research and the vast majority of the public displays, outreach etc, are directly tied to the collection.

Musango comes from ChiShona and means 'in the bush' reflecting the remote wilderness location of the find and the nearby Musango Safari Camp. We dedicate the paper to Wendy Edwards who was based at Musango and sadly passed away while this work was being completed

As someone who has worked on dinosaurs for several years on a PhD stipend, I'm surprised to see all the major news outlets printing, unchallenged, that the going rate for working on dinosaurs for several years is $50 million

Our new 🦕 paper led by @es-ucl.bsky.social PhD student Sam Beeston shows that pneumaticity extends far into the tail in multiple sauropod dinosaur lineages, including brachiosaurids, suggesting that its evolution was probably complex across the clade: onlinelibrary.wiley.com/doi/10.1111/...

New #paleoart of the Welsh theropod Dracoraptor hanigani, restored with appropriately neotheropodan features. UK marine sediments have a glut of small Jurassic theropods, with Dracoraptor one of the best-known. #sciart Like this image? You can own a copy! www.markwitton.co.uk/product-page...
A small predatory dinosaur emerges from the darkness of a Welsh cave into the bright sunlight of a beach. Waves crash over dark rocks, and the sand is bleached almost white by the sun. A solitary cloud occurs in the deep, blue sky. 

It's all fantasy, of course. The weather in Wales is never this good.

Text from article, key sentence "we deduce that the skull had been partially disarticulated prior to fossilization and may have been trampled"

I get a lot of licensing requests for my 2012 #paleoart of (what might be) the oldest known dinosaur, Nyasasaurus. 2012 was a professional lifetime ago, so I've prepared a nicer version for new clients. Nyasasaurus is so poorly known that you could take a recon. in several directions. #sciart
From 2026: the dinosaur-like reptile Nyasasaurus sprints after a tiny beaked reptile, a rhynchosaur, in Triassic Tanzania. Trees, living and dead, erupt from shallow banks surrounding a shallow stream, across which Nyasasaurus has splashed. My old 2012 take on Nyasasaurs, produced in association with Sterling Nesbitt and Paul Barrett. Here, Nyasasaurus examines the remains of an uprooted cycad, while rhynchosaurs munch foliage in the distance. I'd been producing palaeoart semi-professionally for a few years when I created this, but drawing was still a side gig. It wasn't long after I made this image that I began taking my art more seriously, investing in better equipment and leaning more into it as a career.

Ah, I forget I have a skewed frame of reference for early! Coelophysis definitely beats it and the other two sauropodomorphs might once all of their historic taxonomic messes are ironed out.

Under that model it didn't make sense to include pterosaurs within Dinosauria as they are so anatomically and morphologically distinct.

Jack Lovegrove @jackl0vegr0ve.bsky.social · 22/03/2026
On a serious note the idea of "Dinosaurs" as a monophyletic group ( a clade) is relatively recent, for most of the 20th century they were considered separate groups of thecodonts that independently acquired the "dinosaur" bauplan

Pterosaurs shouldn't be dinosaurs because we should keep a taxonomic firewall between them and self respecting ornithodirans...

Specifically Raath argued that Syntarsus could have used feathers to insulate itself from extreme heat, like ostriches do today. So the vaguely emu-like feathers on the model are probably based directly on his thesis

Jack Lovegrove @jackl0vegr0ve.bsky.social · 11/03/2026
Raath was keenly aware of various bird-like features of Syntarsus including speculating about feathers in the 70s so arguably the meme was just reflecting up to date science!

If the paleo community is going to be serious about Horner’s connection to Epstein, we also have to be serious about Myhrvold’s, because guess who contributed photos of animals mating to Epstein’s birthday book and has been appearing in new paleo papers this year - including the new Spinosaurus.
