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! -

I'm also into astrophotography along with all my hunting, fossiling, camping, metalworking, writing... I need to stay busy. Is anyone else on TFF as interested in staring up as well as down? If so, I'd love to see your pics. Here are a few of mine. M31 (Andromeda Galaxy) M42 (Orion Nebula) M57 (Ring Nebula) M82 (Cigar Galaxy) M13 (Hercules Cluster) M3 (Globular Cluster in Canes Venatici) M27 (Dumbell Nebula) Saturn Jupiter Venus Venus (crescent Phase) Moon Close up (Sinus Iridium) Moon, Moon, and Moon Partial Solar Eclipse

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.

I need help friends. A buddy of mine posted a pic of this on FB asking for help identifying it, no one could help. I loved it so I offered to buy it (which I did). This is all the information he could give me. My buddy's uncle died and left him a metal briefcase full of mostly old coins and a few other valuables. He lived in eastern Massachusetts. Items included really old papers, antique watches, coins as far back as the late 1800's and that thing. One interesting item was a fuel ration card from WWII... The intriguing part to me is how defined it is - it must be man made, right? Its about the size of a large coin or small pendant - I'm not even sure it's fossilized, it just looks that way to me. Your help identifying this would be greatly appreciated.
