Scientific discoveries: Acynodon between Technology and Palaeontology

A major study conducted at the paleontological site of Villaggio del Pescatore, in Friuli-Venezia Giulia, has revealed new information on the appearance of the Italian territory at the time of the dinosaurs. This project, a collaboration between the Municipality of Trieste and Zoic s.r.l., led to the extraction and preparation of numerous fossil finds, including those of the rare crocodile Acynodon, a semi-aquatic reptile that lived during the Cretaceous period.
Cooperation with Elettra revealed previously unseen details of Acynodon’s skull that were impossible to obtain before without damaging the fossil. Although similar to a small crocodile, its teeth are surprising: the front teeth are adapted to grasp small prey, while the massive, rounded rear teeth shred shells. This unique adaptation suggests that the Cretaceous crocodiles at the Fisherman’s Village were very different in size, shape and diet to those of today. The results of the research were published in the scientific journal The Anatomical Record (Muscioni et al., 2024).

Synchrotron techniques reveal structural details of fossilised fragment of a rare Australian dinosaur skull

This week palaeontologists from Curtin University announced that a specimen from the collection of the Australian Age of Dinosaurs Museum in Winton Queensland as the first near complete skull of a sauropod, a massive, long-tailed, long-necked, small-headed plant-eating dinosaur, found in Australia and other parts of the world.

The team took 3D images of the entire group of skull fragments, of which a small piece, the premaxilla bone, was scanned in higher detail on the Imaging and Medical beamline at ANSTO’s Australian Synchrotron.

Instrument beamline scientists Dr Chris Hall and Dr Anton Maksimenko assisted with the IMBL measurements and data processing respectively.

“The synchrotron imaging confirmed there were replacement teeth inside the premaxillary bone,” said Senior Instrument scientist Dr Joseph Bevitt, who often assists palaeontologists’ with neutron scanning of fossils at the Australian Centre for Neutron Scattering and the IMBL instrument at the Australian Synchrotron.
