Here is our great big monograph on #fossil #megafaunal #kangaroos of genus #Protemnodon! Six years in the making. We recognise 7 species, 3 newly named, with diversity of locomotor mode. Thanks to everyone that got this over the line ❤️ doi.org/10.11646/megat…

@WoodnuttStacey Ahh I see! That's likely due to their eyes facing laterally - sideways - so they can more effectively watch for predators. This means they will have a small blind-spot directly in front of their nose.

@IsaacARKerr I was curious because the kangaroos over my fence cannot see a thing up close. If I throw food right in front of them (no obstruction to see the food) they will sniff all around them until the finally bump into it. They do spray a lot of glyphosate where they does that cause bli

Should've happened a while ago, but I'm saying goodbye now to this burning train being driven headlong into oblivion by a world-destroying, wannabe-fascist little man-child. Come join me where the sky is Blue and my handle is the same as here xo

@WoodnuttStacey Hi Stacey, I don't know of an inability in kangaroos to focus on close objects. But they do have fairly poor colour-vision compared to many placental mammals (eg. humans) & have relatively good hearing & smell. Probably because they're night/dusk-dawn active, when light is low.

@IsaacARKerr I just wanted to ask you a question, do kangaroos have good eyesight? Can they see close up or only distance objects. Thanks

Exciting news! The free, online Skeletal Atlas of the #Echidna is here! Thanks to @marsupialtapir & all for bringing this beautiful resource to life. #zoology #wildlife #palaeontology #monotreme #skeleton westernweb.net/2024/12/10/ske…

@aNATomy_Lab @_TomMansfield @MosesOmogbeme @NTay_ Aw brilliant! Well done Natasha!!

Huge congratulations to recent #PhD #graduates from the college of #Enviroment and #LifeSciences Murdoch University - @_TomMansfield @MosesOmogbeme, PhD and especially, my amazing @NTay_!! Such an enormous achievement, and just so proud of you 🌟🤗🦘

You mean mass redundancies, the evisceration of entire disciplines, rampant managerialism, and the fanatic embrace of a profit-driven model of scholarship haven't fostered a climate of open inquiry and big ideas? Who could've known?! 🤷‍♂️ theguardian.com/australia-news…

Heck, when you see it all lined up like that... it's absolutely as bad as it seems.

@RobinSSci Sweeet!

On newsstands now...

The description of the skull of Genyornis newtoni, a giant anseriform, is finally out, tandfonline.com/doi/full/10.10… after years of work, this skull has revealed so much more about this bird and its relatives than we could have hoped for. @Blokoweka and Trevor Worthy

abc.net.au/news/science/2… beaut article from @ABCscience about @Blokoweka's amazing #Genyornis #reconstruction!

Another new paper looking at how both the size of an animal and its diet together influence skull shape - this time in rodents! 🐭💀 Well done team! @WeisbeckerLab @aemarcy @TGuillerme onlinelibrary.wiley.com/doi/10.1002/ec…

Very honoured to have been a contributing scientist to the new #megafauna documentary by @ABCaustralia which is now live on #ABCiview. The production team and the scientists are wonderful. Very highly recommend watching the new series Megafauna: what killed Australia's giants?

The trip was generously funded by an Australia & Pacific Science Foundation grant.

Back from the trip of a lifetime to #papuanewguinea, 2 weeks in the Bulolo area digging for #fossils in the Pliocene Otibanda Formation. Thankyou to @MuseumPNG, & to the welcoming & generous people in Saksak village for trusting us with your place & knowledge, we'll be back soon!

The best thing about digging in PNG is you never do it alone. We owe just about every fossil we found to our good mates at Saksak

Thanks also to the trip's unofficial sponsor
