New #DAWNDINOS paper!
We do predictive simulations of vertical height jumping in the Triassic theropod Coelophysis & extant (tinamou) bird Eudromia. Mainly as sensitivity analysis of what parameters are most important. We show how crucial tail mobility is.

Great! Hoping Saura et al team can share too about the Gargatuan-sized reefs in the type locality of the Tafraout Fm!

Congrats @sinjinis.bsky.social @rowanmartindale.bsky.social

I can tell your work will be reflected too in the Tazoult area!

Hoping for papers describing the biota (Serpulids, Bivalves, Bryozoans, Gastropods, ...) too!

Top left: Map of Chile and Argentina with the study location indicated in red.
Top right: two thin section photographs showing internal structures within new wood species Sahnioxylon chubutensis (MPEF-Pb 13152): on the left a general view of the pith and primary and secondary xylem (scale bar 500 microns); on the right tracheids with scalariform and araucarian pits (scale bar 100 microns).
At the bottom, a photograph showing two growth rings within Sahnioxylon and plots to the right showing cumulative sum of deviation from the mean radial tracheid diameter for those rings. On the plots, the proportions of earlywood and latewood correspond to yellow and red shaded areas respectively.
Bottom right corner: cover image for journal Papers in Palaeontology.

The new iguanodont with novel skin coverings. In addition to the large scute-like scales on the tail, the body is covered with what the author's describe as "spikes". The largest ones are about 4 cm long but almost a cm thick, resembling short quills. The smaller ones are hair or eyelash-like.

This Jack Horner. Who’s been known to the whisper network for some time now. There’s a reason I have repeatedly turned down writing about his work or him.
