Thylacines are an icon of extinction, with #NationalThreatenedSpeciesDay observed on the anniversary of the last animal’s death. But its final resting place has been subject to an 86-year-old mystery, solved this week after a discovery in the TMAG archives. 1/6

On #TrilobiteTuesday I'm keen to say my first lead-author paper is, at long last, published in Evolution Journal! We find that segments developing in the tail region of trilobites follows a simple developmental rule that matches what is seen in vertebrates. academic.oup.com/evolut/advance…

New paper from my PhD is out now #OA! Koalas and wombats use their forelimbs for pretty different stuff - is this reflected in the topology and architecture of their muscles? 🤔💪 Physical and digital dissections show us they're surprisingly similar! doi.org/10.1093/zoolin…

Key topological differences included a large insertion for Trapezius on the wombat humerus, while the koala had big Teres minor and Coracobrachialis that were missing in their bulkier cousins. Likely reflects differences in mobility requirements of the shoulder.

The koala had more differentiated muscles to their digits too, enabling fine grasping control, rather than the stout, spade-like hand of the wombat that seemed to operate more as a single unit.

How is this useful? The quantitative PCSA data can aid studies exploring patterns in mammalian forelimb muscle architecture. But crucially, koalas and wombats bracket a huge diversity of extinct vombatiforms, so their anatomy helps us infer muscles in fossils like Palorchestes.

There are interactive 3D versions of the figures on Sketchfab, made from our #diceCT and MRI scans - have a play! Or peep the supp material for juicy dissection photos if that's more your speed. skfb.ly/oJ6NE skfb.ly/oJ6NF

Come chat to me about this or other functional morphology stuff at #ICVM2023 in Cairns at the Saturday poster session, 4pm 29 July! Thanks to coauthors Alistair Evans & Justin Adams, and to Dr David Hocking for the title (evoking my mood trying to finish this study during COVID lockdowns)

New paper by my colleagues and I on the reproductive anatomy of a leopard seal 🦭 Leopard seal reproduction is mostly unknown. This note from a Monash University dissection discusses the importance of morphology in providing some clues. Open access paper here: doi.org/10.1111/mms.13…
