Witmer, L.M. 1997. The evolution of the antorbital cavity of archosaurs: a study in soft-tissue reconstruction in the fossil record with an analysis of the function of pneumaticity. Journal of Vertebrate Paleontology 17(Supplement 1): 1-76. doi:10.59350/bvpaq-czq07 Posted by Matt Wedel F...
Parting shot (and an excuse to post a photo for Fossil Friday): on my Tate trip this summer I hit a gang of museums, and everywhere I went I found pneumatic sauropod ribs. I think there are a lot more of these things out there than most folks have appreciated. I’m proud of my r...
According to experts, this is an astounding breakthrough which greatly contributes to humanity's record of itself and understanding into the lives of the common ancestors from which we evolved.
Scientists can’t get useful genetic information out of every fossil they find, especially if it’s really old or in the wrong climate. They haven’t been able to gather much ancient DNA from Africa, where H. sapiens first evolved, because it has been...
initial publication and analysis of 1,000,000 base pairs of the Neandertal genome led the researchers to make the following conclusion:"This high level of derived alleles in the Neanderthal is incompatible with the simple population split model, given split times inferred from the fossil record. ...
We have to construct, by straightforward thinking on the basis of very few factual observations, a plausible and self-consistent picture of a process which must have occurred before any of the forms which are known to us in the fossil record could have existed. ...
is exposed to high regulatory-transition risks with 52,000 megawatts of fossil fuel-generating capacity in the country, where carbon prices would need to rise significantly to limit climate change to 2 degrees C. Similarly, an energy infrastructure company based on the U.S. West Coast is ...
We also know the atmospheric increase is from burning fossil fuels because of the isotopic signature of the carbon in theatmosphere. Carbon comes in three different isotopes, and plants have a preference for the lightest one, carbon 12. Anything that eats plants, or eats things that eat plants...
Opening Line Idea: Snow fell, creating a blank canvas to record the story of that fateful walk.Jump-Start Questions: How would you feel if you were walking in the snow in this scene? How would you find out what made the tracks? How far from civilization was this picture taken?Train...
Fossil vending machine in the BYU Museum of Paleontology. All casts, except for the shark teeth and pieces of Campo del Cielo meteorite. They also have bigger casts for sale in the back. My brothers Venmoed me money for my birthday. BYU takes Venmo for fossil casts. That’s how I got...
