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

Ok, i know that barnacles are arthropods. But, i can understand the anatomy. It is a shell that the animal make for "home" and the animal is free from this, or the shell is part of the body? Can an adult barnacle moved?

Hello everyone, I found the below ichthyosaur vertebra on the beach at Wimereux two weeks ago. It had obviously been lying there for some time, as it was covered in green algae and barnacles. Based on the advise of various friends and the fact this rock seems to hard and massive to work through using just my Dremel, I'll be leaving the fossil in its matrix. However, I do want to clean it up from the algae and barnacles. As such, I used a 1:2 dilution of 14° household cleaning vinegar and a couple of sturdy brushes to remove most of the algae (dipping the br

Hi Fossil and rock hounds, I found this strange looking piece when looking through my shark teeth. Found it on Manasota Key beach, Florida. I thought it was some vertebrae bone but than I saw 2 barnacles in what might be a grouping of shells. It also has pockets of limestone and small black bones or rocks cemented in some of the pockets and has some weight to it. It is about 2x2". Posted 5 photos of different angles. Has anybody ever seen anything like this? What is it? Thanks All.

The Peace River is a magic place, It always has surprises in store, even when I am finding little that is Spectacular!! Look at this selection found while hunting today. Some NICE Hemis, a flake from tool making, even a wild boar tusk (hollow inside and modern) and then The botryoidal translucent brown mineral growing on the fossil is chalcedony. Chalcedony often fills the empty spaces in fossils, especially wood and bone. Did I mention a calcified sea urchin spine .. NEAT !!! Even got 1 Meg (very 1st find of the day), and a couple of calcified Barn

Hey all, I am working on a project within the Glen Rose Formation of Spring Branch, Texas. Could somebody take a look at these giant forams (Orbitolina texana) and see what the binding organism is. I originally thought they were oysters but now my professor suggests that they make be barnacles instead... These forams are roughly half a centimeter in diameter
