It's not related to fossils, but astronomy is one of my other passions. I've managed to snap a few photos over the years.... Comet Halley, March 1986: Comet Hale-Bopp, March 1997: I hope to capture Comet ISON later this year.... Eclipse at sunset, May 2012: Venus transit at sunset, June 2012: Both events at sunset within a month.... What are the odds? Anyone else have astrophotos?

Hello Everyone.. New Member From San Bernardino CA
HideousCorrectness posted a topic in Member Introductions
Hello! My name is Elaine Scott. I am a new member to the forum. Exploring the mountains in the high desert and rock/fossil hunting is a hobby of mine. I have a small collection of interesting items. Some of which I will ask for help identifying, I look forward to feedback! I see there's soo much content to explore on this site I'm pretty sure I'll spend the next several hours (and many more in days to come) scrolling through it all. I hope everyone has a great day! -

This piece was excavated out of a block of matrix deposited in the Chesapeake Bay by a landslide. The shell was partially exposed in the water. The dark side was still in the matrix while the light side was exposed to the water. The pock marks on the light side are from modern barnacles which I removed during preparation. L. heros is a species with variation in shape. It may have a taller or flatter spire and the overall shape may be more or less globular. This specimen was donated to the Delaware Museum of Natural History.

Lunatia heros is a predatory snail that drilled holes in other mollusks' shells to eat the contents. One often finds hole that they left behind in the surrounding fossil shells. The shells of L. heros are variable, having more or less extended spirals, more or less globoular shape, etc. This specimen was donated to the Delaware Museum of Natural History.
