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!!!!
