These 2 scallop sea shell fossils would make a great addition to any collection!! they were found by my Father-in-Law when they dredged the Miami River. He went there many times and got lots of fossils! One has barnacles on it and the other one has a lot of sediment inside. They both measure 1" across shell. I have lots of shells and shell fossils up for sale and gladly combine shipping! Thanks so much for stopping by!
