abyssunder Posted May 18, 2017 Share Posted May 18, 2017 Pictures are a bit blurry, but if the holes on the surface (visible in the second and third image) are 'boreholes', it could be a bivalve, something along the Rastellum line, I think.

Doesn't look like Calamities, more like a bivalve. But it doesn't have the characteristic zig-zag pattern of Rastellum or similar species, so I'm not sure what it could be. The line down the middle looks almost like the stem of a fern. Sharper photos might help. Link to comment Share on other sites More sharing options...
