Weighing Dinosaurs (and other animals) with Meshlab

A couple of years ago, I was part of a group that published a method on calculating body mass in extinct animals from laser scans of their skeletons. The method involves separating the model into parts, and then using the qhull command to produce a volume that encloses the segment as tightly as possible. This... Continue Reading →

It's a bit of a long title,... Continue Reading →

Not Just Pretty Pictures…

Digitization is no longer just a novelty – it is absolutely vital to good analysis and communication of data, and it’s so easy more people should be using it. Most people reading this blog will probably know what photogrammetry is, and it’s not my aim here to discuss the method per se. Suffice to say... Continue Reading →

Fossil Swimming Hippo TracksThis paper isn't quite out yet, but it's showing in google scholar, so I guess it's worth putting up on my [non-promoted] blog. Matthew Bennett, at the University of Bournemouth led on this one, in which we describe possible hippo swim tracks from the Koobi Fora footprint site in Kenya (site of ancient...
