Long shot, could these scratches on an eggshell be predation marks?
FF7_Yuffie posted a topic in Fossil ID
Another curious little piece with multiple tiny scratches. Its a long shot, but could this be some type of predation? The shell is only 2 cm long though. Its the only shell piece among the bag with scratches on it like this.

Hey everyone, long time lurker here. Got a case of mistaken identity, hoping someone can point me in a direction however vague, though I know it's a longshot since there's no location/formation info. I'm sorting out some storage boxes and found a box of assorted fossils from when I was a kid, mostly gifts and things found in tourist shops, junk/charity shops etc. I vaguely remember this being from the latter... and it's in a nice little box with a label... only problem is, that is NOT a brachiopod! XD Anyone recognise this one? I'm in the UK, not that I suppose it makes much difference. Sorry for the photo quality. Hopefully they upload ok. Scale is in CM, shell is about 5.5cm long.

Hi everyone this is Matt again. Can anyone tell me what kind of shells these are ? They are all over the fossil.

I went collecting at the Eocene Whiskey Bridge Locality and found a number of oysters (I presume) that I cannot find good IDs for online. I was wondering if anyone here had a better idea. I additionally found some bone fragments that I am curious about, though I don't know how well they can be ID'd.

Members of the Hamulus genus are easily confused with Scaphopoda (tusk shells) and were originally identified as such. The shells are curved tubes ending in a point, with smooth interiors. Hamulus squamosus begins with less pronounced ornament and grows wider longitudinal ridges as it matures1. 1. Survey, Maryland Geological.

When I was a kid I found this bivalve fossil and now looking at it, I think it lived attached to something on one side. You can see how one of the shells is deformed in a wierd way. Is it a known and common phenomenon? Also I would like if one of you can help me get an ID on this bivalve.

Found in the Mount Laurel formation of the C&D canal Delaware. It looks like a modern day razor clam. Does anyone know the genus of this fossil?

What is the age of the oldest known non-permineralized shell?
Eye in the Sky posted a topic in Questions & Answers
Recently, a group of paleontologists were having a discussion regarding fossil shells after a woman produced one for identification. Discussion turned to the difference between a shell and a fossil shell (that being a shell which has permineralized). There was debate as to whether or not there are any shells that are older than any fossil shells in the general paleo record. One of the paleontologists knows a shell expert and she reported back that the oldest known shell is approximately 18,000 years old and that all shells older than that have permineralized. However, some found this difficult to believe, as shell material, being mostly calcium carbonate, should be able to survive for very long periods in non-acidic deposition environments. Can anyone confirm this? Thanks! -
Not sure what this fossil or structure is. I found it in my neighborhood in North San Antonio where there’s a lot of limestone and fossils in limestone and petrified wood. I’m in a new neighborhood and thee builder has to dig through lots of stone to bury utilities and set foundations. this little object reminded me at first of a baby oyster shell due to it’s oyster shel shape. When i got it home though and looked at it under my magnifier, a huge question mark formed in my mind. The ‘rosette’ structures which appear to form it have me confounded. I wonder if it might be barnacles or coral and wonder if the shape is coincidental to looking like a shell. Can anyone lend some expertise? Any help is greatly appreciated!!!!

Hello, Sometimes I collect shells from the beach and the other day I found the one in these pictures. My friend thinks it may be a shark tooth but it looks unlike other shark teeth I've seen. If you have any idea what it may be please let me know! Thank you.

Recently found a very large area covered with these shells on our ranch after a rain storm. It is in sweetwater county, south western Wyoming. Just curious what they are, what time period they are from, are they the kind that produce pearls, just a general knowledge of them. Any help would be great, thank you.

Hello, I'll admit I have zero experience with fossils. One day while waking or property I found this fossil. I am interested to discover what it is and how old it may be. It was found about a mile east of the Trinity River near Palestine, TX. I was surprised that it was on top of the soil, but the area is prone to erosion. It's about 2 inches in length and has some obvious texture to it. Hopefully my pictures are clear enough for identification and/or dating.
