paleontology

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,

Trilobite: Eyewitness to Evolution

Richard Fortey, 2001, ISBN 978-0375706219

If you’ve driven the long way across Kansas on I-70, there are two things that you’ve seen and wondered about.

First and foremost, Wheat Jesus on a billboard in Colby, Kansas. I have no insights, artistic, theological or sociological, on Wheat Jesus, or “Wheatus” as some folks know him.

There’s also the big beige dome on the south side of I-70 in Hays, Kansas. That’s the Sternberg Museum of Natural History. You really should take an hour or two to visit it. Well worth your time.

A Museum You Should Visit

Fossil Butte National Monument is about 20 miles from Kemmerer, Wyoming, and well worth a visit.

A paper worth reading:

Tihelka, E.; Howard, R.J.; Cai, C.; Lozano-Fernandez, J.
