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!- 3 replies

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.

Found this little clam type full mold in NJ Cretaceous stream (not Big Brook). First time I've found a shell mold like this there. Reminds me of the Coquina clams in the undertow along the Jersey beaches in the summer. Any info on what it's nomenclature may be? Fun highlight of the day outside of the common shark teeth.

Found this in my yard in SW Washington long ago. Looking over what I believed were my fossils, I noticed what appears to be the clam in the shell I thought was fossilized. Is it? Not sure where the shell was originally found. Possibly So. Washington or Oregon coast. measures 4 cm. I can feel it.

These two rocks were found in East Texas, mostly Eocene. Property is on Carrizo-Wilcox aquifer. Dry land in wooded area. I've read some about how hematite is formed so I guess this is normal to see a shell and what I think is matrix? Is the shell a print or a shell? Idea of age? Then there's the tubes in the second rock. Is that what those are? Thanks so much for any help.

This new site I’m going to is kind of starting to grow on me! I really love the abundance of well preserved shells and the sharks teeth that come out of here (if I don’t break them) are in superb condition. I arrive at this site, however, with some disappointment. Footprints everywhere, and discarded rocks piled in a pile i know I didn’t leave with a bunch of broken shells. It looks like someone took the liberty of smashing rocks with a hammer and leaving the place a mess for others. Not a good look to be honest I always try to clean my area and make it look better than where I left it. The good news is whoever the eager beaver was left some goodies behind. I searched their rock pile of discarded rocks and found a lot of shark teeth in very good condition that were just left there. I wonder if this person was too busy picking up pennies to notice the quarters they were stepping by? Anyways here’s the haul, luckily I didn’t have to put in too much effort since this person did all the hard work for me: total haul: shark teeth (not in the rock): crocodile tooth (happy about this one!): shells: Shark teeth in the rocks: And the killer tooth of the day: Most of these finds we’re not made because of me ripping rocks out Willy nilly, but because of me sorting through said rocks after this person ripped them out Willy nilly. Always be thorough with your excavation and be patient. You never know what might be hiding in the discard pile. Part 2 of my trip to the Chesapeake will be posted tomorrow!

Hello everyone! My little brother made this nice find near Thrupp Lake in Abingdon, Oxfordshire, UK. The lake is close to the Thames river. It looks like some sort of shell fossil? The rock is about 8cm wide and 5cm tall. We'd appreciate any help identifying it! Thank you.

Helotes, Tx Part of this shell was sticking out of a chunk of sediment. I used a water pick to clear the rest of it. In trying to determine what kind of shell it is, I’ve found several that are similar, but none with the shell spiral as tight. The closest thing that I could find is below. This doesn’t seem correct considering my location. Placostylus porphyrostomus is a species of large air-breathing land snail, a pulmonate gastropod mollusk in the family Bothriembryontidae. This species is endemic to New Caledonia.
