For today’s post, I want to show you an astounding piece of art I commissioned to Ida Kalsta, an extraordinary illustrator and artist. This represents an environment from the Early Cretaceous (Aptian, ~116 millions of years ago) of Patagonia, in particular the possible environment of the Ticoa harrisii fossiliferous layer in the Anfiteatro de TicóContinue reading “A day in the Cretaceous of Patagonia”

Forgotten formations: Anfiteatro de Ticó.
While doing some doomscrolling on Twitter, I came across this absolutely spectacular reconstruction of the Triassic Fremouw Formation by Liam Elward. The main focus of the piece are a couple of Lystrosaurus, but the attention to the flora of this formation is stunning. Many plants are known from the Fremouw formation, with many having beenContinue reading “Forgotten formations: Anfiteatro de Ticó.”
How to represent uncertainty in phylogenies: RoguePlots to the rescue!
In my short research career I have become more and more intersted in how to appropriately represent uncertainty in phylogenetic analyses. Phylogenetic trees based on morphology are often represented as a single (strict or majority) consensus tree, sometimes with branches labelled with branch support (bootstrap/jackknife percentages or ‘Decay index’). However, in many cases this formContinue reading “How to represent uncertainty in phylogenies: RoguePlots to the rescue!”
