Hopefully this is the right place. This is part of a collection that I inherited from my Mom who inherited it from an elderly lady she took care of that was heavily into archaeology and artifacts in her younger years.

I found two notes with this collection "Trilobite Middle Cambrian Millard County Utah" and "Dinosaur Gizzard Stones"

I know absolutely nothing other than what the notes I found say. :icon_scratch: Any clues? :dontknow:

Here are photos front and back...

cool rock collection, two look like petrified wood
and the two kinda crystalized looking ones are either
calcite, or barite, the rest look like jasper.
 

hah, Dinosaurs swallowed small stones to help digest food the way chickens do today
 

But unless you find one (or a pile) in the torso of a dinosaur . . . how would it look different from a river or stream cobble?
 

I can't speak to the gizzard stones. They would have had to been found in association with a dino skeleton. The other item, I believe she mixed up trilobite with ammonite. That is a section of ammonite from before they evolved into a tightly coiled form. If you look closely you can see the suture lines. Ammonite.

Not sure but I do have an unopened box labeled dinosaur bones that was in the same inherited collection of things I now very little about.
 

I agree with BIGSCOTT's impression of things.

As far as the gastroliths go, I have a big one that I got from a tricertops excavation, and it does look like a polished river stone. Unless you have pictures of the gastrolith at the site of the excavation, it's just polished gravel.

It looks like you may have at least ten possible gastroliths in the collection. All gastroliths are not found with their fossilized bones. I have found an area where gastroliths are quite plentiful. This area is where the parent/parents returned from foraging and fed their young by regurgitating the food along with the stones. I have found gastrolith stones that were about an inch in diameter to some that were up to at least three+ inches across. Nice collection.
