Examining under magnification the surface of failed mechanical parts gives a pretty good idea of when and how the break occurred (brittle, ductile, fatigue, etc). This has been developed by looking at parts where you know how they failed. I would expect the same could be done with fossil shark teeth. Sacrifice a fossil tooth and a modern shark tooth by breaking them and use for comparison with future finds.

The attached photos show a specimen I picked up in a rock shop in North Carolina many years ago. They said it was from Pennsylvania or Ohio if I remember correctly (I could be mistaken). Anybody have any thoughts on what it might be? Sorry for the glare in the phone photos. I can take more with an SLR if need be. Thanks.

Were the ants invited guests or did they party crash?

Who is this bird you speak of? Wren from Carolina or Virginia Rail? One must be careful, Red is knot the one you should listen to. When Brandt and that loon Jay get together there are some tall tails. Cliff’s stories are hard to swallow. Was Phoebe telling the truth or just parroting Myna? Townsend will warble more than he knows, like his friend Magnolia. You can trust Ruddy, he will leave no stone unturned. A cardinal principle is to watch what this flock does. Talk is chirp.

The labels look like they came from a fossil company that used to sell mail order in the late 1960’s. I can’t remember the name of the company, but they did have pretty good data on their specimens. I want to say they we out of Texas, but I could be mistaken.

Fossil collecting in the American West in the late 19th and early 20th century. What Sternberg was able to accomplish was amazing. #fossil #method

Fossils of Gumby? I’m not dating the specimens, but I might be dating myself.
