In these trying times, take some advice from a giant extinct marsupial named ‘Ambulator’. Now available from the Toothy Grin online shop.

Siderops.

Some new badges! There’s a mix of new designs and colour variants here. Among them are Antechinus, Trilophosuchus, Sarcosuchus, Deinosuchus, Edenerpeton and Petaurus.

I spent this week at CAVEPS, which is the best vert palaeo conference in Oz + NZ.

Can't wait!

Never expected to see one of my drawings on a beer.

Anyone know what's going on with this strange looking kangaroo... #palaeoart #paleoart #procoptodon #megafauna

@jorgoristevski.bsky.social just alterted me to this absolutely horrible page of false AI slop being passed off as an educational page on the Queensland Museum website. www.museum.qld.gov.au/learn-and-di... 1/n

A couple more reptiles I want to appear in PhP Ice Age are Paludirex and Quinkana. Megalania and the saltwater crocodile weren’t the only large predatory reptiles of Pleistocene Australia. Here I’m going to focus on Paludirex.

If you can't get any aDNA, use collagen instead. I wonder if this technique might help resolve the taxonomy of suggested "dwarfed" species like Macropus titan/giganteus or Sarcophilus laniarius/harrisii?

Well this is as done as it's going to get. Tiliqua frangens, a megafauna skink from pleiocene and pleistocene australia with large pointy scales feeding on spring wildflowers. #palaeoart #palaeoart #reptile #lizard

doi.org/10.1098/rsos... new paper out now with @royalsociety.org on limb structure & function of the #fossil #kangaroo, Dorcopsoides fossilis, from central Australia. The oldest known macropodine (subfamily of all but one of living roos) & a fun glimpse into the great Late Miocene kangaroo radiation

New paper describing the eggshells likely belonging to the early mekosuchine Kambara, possibly indicating a different incubation method relative to modern crocodiles doi.org/10.1080/0272...

Some tideous studies for an upcoming illustration of a certain fragmentary Wakaleo Species, perhaps the youngest of them... Credit to gtg141 on DeviantArt for the W. schouteni and W. oldfieldi skull reconstruction as helpful guides to doing my own reconstruction of W. alcootaensis. #sciart

I'd like to nominate "Diprotodudes" as word of the year.

The news today is making me think of this amended display in the biology building at UNSW.

this has to be one of the cutest animals ever

DROP BEAR!!

(Recent art) Ceratodus nargan Illustration! Ceratodus is a wide spread prehistoric lungfish species that is related to the extant queensland lungfish. Here lies a species in the Early Cretaceous of Southern Victoria, Australia, in the Euremella formation. #paleoart #sciart #illustraation #fishart

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone #temnospondyls #paleoart

The story of extinctions and population depletions in the late Quaternary is a complex one. Climate and humans interference in shaping diversity is always convoluted. Here is the story from the Australian lizards' point of view 👇 www.cell.com/current-biol... 🧪 ⚒️ #Paleobio #Macroecology

Prototype greeting card, featuring Psychrolutes (A.K.A. “blobfish”).

(Old Art) Leaellynasaura Illustration! I haven't posted this here yet, so just gonna show it here. I have depicted a "Months of Light Seasons Morph" (Dark Variant) and a "Months of Dark Seasons Morph" (Light Variant), Inspired by old illustrations with different morphs in books. #sciart #paleoart

Orca sized lamniform sharks from the Aptian of Australia: "Our results show that mega-body size is an ancient lamniform trait, with the Australian cardabiodontid being around 6–8 m and over 3 tons."

🦴New fossil alert🦴 Introducing Aeviperditus gracilis, a possible bowerbird from the Miocene of New Zealand. My first fossil description! Artwork by the amazing Sasha Votyakova (Te Papa CC-BY-SA) (🧵1/11)

Red rocks of McGrath´s flat contain countless #fossils of the 11 MYA wet Eucalypt forest, probably not unlike this Watagan Ranges forest, near Newcastle, AU. New paper by colleagues from AusMus in Sydney explain how this diversity of forest fossils was preserved tinyurl.com/5xzjrtnr 🦖

Another from early last year of Progura campestris, a pleistocene megapode bird, encountering a monitor lizard. This one was inspired by getting called at by a malleefowl when I accidentally got too close to its nest 😅. #paleoart #palaeoart

For #Croctober Day 20 I want to shout out some fun etymology. To the left you see Paludirex, a large mekosuchine who's name means "swamp king". On the right is Gunggamarandu, which translates to "river boss". Both have been named by Jorgo Ristevski Art by Eleanor Pease

Valentyna Inshyna has supplied this amazing palaeoart with Rhaetosaurus brownei, Cavendrichties sp and newly described by us Telmatiomyia talbragarica fly, reconstructing late Jurasic of Australia #fossils 🦖🧪⚒️https://tinyurl.com/2v3kx4h7

I should boost this.

There are now 18th C papers with DOIs.

Mutt!

#Croctober Day 6 Heres a fun one from a research history POV. In 1997 researchers described a snout tip under the name Baru huberi and in 2016 skull elements were given the name Ultrastenos willisi Only last year did we recognize that both fossils belonged to a single individual

For #FossilFriday, an ichnological 2-for-1 special in a body fossil: a termite nest packed with termite coprolites (feces) in an araucarian tree trunk, from the Early Cretaceous (~125 mya) of Victoria, Australia; oldest termite nest in Australia & largest wood nest from this time. 🧪🪵🪨⚒️ #ichnology

Digital exhibits done right.

Any palaeoartists drawing extinct marine turtles may find this useful.

Longman's Beaked Whale! This was originally described on the basis of a skull that washed up in north Queensland. It was yonks before the living animal was recognised.

There's a new bettong in town! Like most bettongs, it's already extinct.
