It really shows the complexity of earth systems. Think about the sub categories and ranges of potential values for each (not to mention the ability to measure those values accurately) of these cards’ topics. No shortage of things to study.

You don’t get to see a movie star in person very often, let alone photograph them.

Just a question Jeanette. Would you say it is a very young mastodon because its teeth don’t look very worn? Thanks.
-
It’s not very young, but it’s not a full grown adult. I would classify it in the teens, on par with the age class we keep seeing with the Gomphs at Montbrook as well

Thanks!

Record size for Montbrook?

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?
