Hello everybody. I was a geologist in a previous life (Liverpool University 1999) and had never really found anything interesting. I was picking some oversized from a clay lining system we are deploying and came across this oddly shaped rock. On inspection it looked very glassy, almost like chert would inside. But the shape looks so much like a joint I wondered if it might be a fossil. The bulbous end is very pitted which reminds me of bone, but where it has broken it is very polished. The clay is (was) an alluvium deposit from Cardiff area (river Taff) I think, there are Jurassic rocks near by. I still do a bit of earth science work with Cardiff Uni and will take it down there if I get the opportunity, but would welcome any thoughts in the interim. now its been a long time since I did any rock or fossil identification so please be kind!

This weird mineral was in my collection. It’s glassy and smooth. Does anyone have an ID for it? Thanks! (It’s like a growth on a rock, not the whole piece)

Been looking at this and trying to decide how to approach it. Have at it. I can do close ups on the flats, but not the radius of the, dare I say, shell.

Hello I am a rookie again at 67yo. I have a just posted the clam shell seen here on another post and am wondering about these tubular corral looking runs I have found on the beach along with many other types of fossils. Any ideas ?? The tube in jpg.023 looks like a glassy center, very shiny. I tried to detect an odor but the river water I think masks any odor. These tubes range 3' and more, running in curves with off shoots and branches reminding me of corral. When I found these I was totally not prepared to collect or carry much so this is a broken off piece. Along with the clam shell how do I prepare this type of fossil/// any help would be great. I am on the Eastern shore of Maryland, approx. 30 mile due east of Calvert Cliffs, Maryland. David
