paleontology

I read yet another paper about the Ordovician period:

The Great Ordovician Biodiversity Event (GOBE): definition, concept and duration by Thomas Servais and David A.T. Harper, Lethaia, vol 51, pp 151-164

There is a PDF of it.

Interesting paper:

Impact-induced initiation of a Snowball Earth: A model study
Minmin Fu, Dorian S. Abbot, Christian Koeberl, Alexey Fedorov
Science Advances, 10 eadk5489 (2024) 9 February 2024

I read a paper, Oxygen and animal evolution: Did a rise of atmospheric oxygen trigger the origin of animals? by Daniel B. Mills and Donald E. Canfield, BioEssays, Volume 36 (12) - Dec 1, 2014

I can’t find a good, free, PDF of this one, mateys.

A Museum You Should Visit

The Morrison Museum of Natural History makes a good pair with a visit to Denver area Dinosaur Ridge.

If you’re in the Denver, CO, area, you really should head out to the western end of Alameda Boulevard, where you’ll find Dinosaur Ridge. You can see Apatosaurus footprints, and just possibly, the remains of Tyrannosaur Rex courtship rituals.

I read a paper, Skeletal pathologies track body plan evolution in ichthyosaurs, by Judith M Pardo-Pérez, Benjamin P Kear, Erin E Maxwell

I read a couple of papers dealing with Ordovician period geology and paleontology.

Evidence suggesting that earth had a ring during the Ordovician, Andrew G Tomkins, Erin L Martin, Peter A Cawood, Earth and Planetary Science Letters, 646 (2024)118991

Understanding the Great Ordovician Biodiversity Event (GOBE): Influences of paleogeography, paleoclimate, or paleoecology?, Thomas Servais, David A.T. Harper, Jun Li, Axel Munnecke, Alan W Owen, Peter M Sheehan, GSA Today, April/May 2009

I read a paper: The nature of the last universal common ancestor and its impact on the early earth system

Even though the abstract includes the word “iconic”, I recommend an article from Nature, Uniquely preserved gut contents illuminate trilobite palaeophysiology,

I read a pre-print of a paper, The origin and early evolution of arthropods,
