Interesting talk from Nigel Goldenfeld about the scaling properties of phylogenetic trees and the general features of evolutions. www.youtube.com/watch?v=iwjS...#Geology#Paleobio#EvoBio
Long-memory effects is a general feature of complex Earth system phenomena. It applies not only to hurricanes and human casualties on short time scales, but also for the mass extinctions and macroevolution at the longest time scales. doi.org/10.1017/pab....#Geology#Paleobio#EvoBio
New study led by Michela Johnson on the histology and ontogeny of what is probably the best sampled thalattosuchian (Macrospondylus bollensis) from the Lower Jurassic of Germany. 🐊🧪 #paleobioanatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
The Posidonienschiefer Formation of southern Germany has yielded an array of incredible fossil vertebrates. One of the best represented clades therein is Teleosauroidea, a successful thalattosuchian ....
This is quite dramatic. The Cambrian and the P-Tr boundary are rad's. Here are shown relative contribution of different groups in reef building during the Phanerozoic from just published "Palaeontology" article: onlinelibrary.wiley.com/doi/10.1111/...#Geology#Paleobio#EvoBio
Interesting freen hybrid conference about the habitability of planets and the evolution of biosphere: "Chance and purpose in the evolution of biospheres" royalsociety.org/science-even...#Geology#Paleobio#EvoBio
Discussion meeting organised by Professor Philip Donoghue, Professor Anja Spang, Professor Tim Lenton, Professor Samir Okasha, and Professor Graham Shields.
Cool discovery, but shows a case of bias, when phylogenetic assumptions colour the biological ontology: "[polar bear] diverged from their closest relative–the brown bear" www.popsci.com/environment/...#Paleobio
Scientists are solving the mystery of when diverged from their closest relative–the brown bear.
Earth probably had rings during the Ordovician. This is implied by the intense asteroidal bombardment during this period, and the concentration of impact structures around the paleoequator. www.sciencedirect.com/science/arti...#Geology#Paleobio
I think @dwbapst.bsky.social nailed it when he pointed out that the main message of the paper is that fossils aren't a magic fairy dust that you can sprinkle on an analysis to goodify it. There's a lot of complexity to the FBD, as there was with all the quantitative paleobio methods before it.
Finally arrived—the physical copy of the "Macroevolutionaries: Reflections on Natural history, Paleontology, and Stephen Jay Gould" by @bruceslieberman.bsky.socialnilese.bsky.social#Paleobio#EvoBio
