Thomas74P Posted July 4, 2022 Share Posted July 4, 2022 I found this along the shore. It appears to be formed in sandstone but the fossil looks like it's the same hardness of fossilized bivalve shell. As you can see in the left side picture the fossil has 5 petals and an empty circular center which is now filled with sandstone. The middle picture shows the fossil dry. The 5 petal like structures are almost invisible when dry. The third picture on the right shows the back side of the fossil. I placed it next to an old penny, they're nearly the same size. If anyone has any info on it I'd love to hear what it's name is. I'm hopping it's a Sand Dollar. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted July 4, 2022 Share Posted July 4, 2022 No idea what the coin size may be, but, yes, that's a fossil echinoid. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
