Perna are an extinct genus of bivalve, they are from the mytilidae family, the same family which include modern day muscles, and this can be easily concluded when the shells are observed as they look quite similar in shape. It is unknown what the exact species is, however, it is known that these fossil specimens are Jurassic in age, making them between 200 to 145 million years old. They were collected from the famous Coober Pedy locality in Australia, a location more well known for it's opal deposits. The specimens are roughly 3 cm in length and come supplied in a packet with an information label.
