Lots Of Ids Needed


TyrannosaurusRex

Very interesting looking finds. The second one looks geologic, like layers of sediment. The 7th one is an ammonite and the 13th one is an impression of another ammonite. Sorry but I can't tell anything about the others. Maybe someone will recognize some for you.

The fourth one looks like a sedimentary rock with a bunch of pieces of shellfish in cross section. The largest shellfish section appears to have a lining of crystals. The crystals are possibly calcite and possibly quartz. If they are calcite, they will fizz if you place a little vinegar on it. Otherwise they are probably quartz. The ninth one may have a trace fossil - specifically a worm tube.

The last one petrified wood?

Look at it in the cross section direction. Does it look like wood? If it does, I'd say it is petrified wood. (If necessary, clean that surface up real well so you can see it better.)
