Excited to share our research on the evolution of fossil forests from the Devonian to Jurassic! By analyzing 38 global fossil forests, we explored key parameters to better understand how these fossil forests developed over time.

Also also: this room done up as a cabinet of curiosities was fun.

Room with deep red walls and floors, with an ornate chandelier. The room includes a mastodon skeleton and a host of stuffed birds in cases. There is no interpretive text to be seen--just stuff.

Also: this lovingly restored reptile display in classic mid 20th century style.

Display reading "Life histories of Michigan reptiles" featuring irregularly shaped, overlapping solid-color panels with text and models of a snake and turtle.

Diorama of a Michigan deciduous forest in early autumn, with foliage still on trees and ranging from yellow to red. A male whitetail deer is in the background, partially concealed by a tree.

A small group of whitetail deer emerge from the edge of a corn field where it abuts a forest.

Fall breaks for U-M and AAPS coincided, so I took the kids to West Michigan and stopped at the Grand Rapids Public Museum for the first time. Home to some beautifully done dioramas depicting Michigan ecosystems.

Diorama depicting a pack of wolves on a snowy night, stalking prey visible in the distance.

Diorama of a moose family congregating around a pond.

Diorama of a west Michigan scene depicting the transition from a forest to a sandy set of dunes along the Lake Michigan coast. An Igloo cooler and pair of hiking boots lie in the sand at the middle of the scene, suggesting someone has left them there at the start of a hike.

Diorama depicting a deciduous forest, with an owl in a low tree branch and a fox and kit scampering past a fallen log on the forest floor.

Spookiest decoration at the "Zoo Goes Boo" event at the John Ball Zoo in Grand Rapids? Giant model of parasitoid wasps hatching from cocoons affixed to their caterpillar host.

Large model of a green caterpillar, the back of which is covered by dozens of white cocoons. Wasps can be seen emerging from some of the cocoons.

First post here to show a bit the work I did with Joëlle Barido-Sottani and Hélène Morlon on phylogenetic diversification models with heterogeneous rates in a Fossilized BD Framework
🦴:
www.biorxiv.org/content/10.1...
The paper is still under review but the method is already available in BEAST 2 !

The Fossilized Birth Death Process with heterogeneous diversification rates unravels the link between diversification and specialisation to a carnivorous diet in Nimravidae (Carnivoraformes)

Bayesian phylogenetic inference uses more and more complex diversification models as tree priors to test new macroevolutionary hypotheses. However, those models are usually developed in a neontologica...

This is the only "complete" crinoid in my collection, from holdfast to crown.

It's easy to see why they are sometimes called sea lilies, even though they are animals related to starfish and sand dollars.

This is Abatocrinus gallatinensis from the Mississippian Lodgepole Fm of MT.

#FossilFriday

Crinoid with "feathered" arms, long stem and holdfast root system.
