Unidentified South African Lower Cambrian
This was found on a geological field trip to South Africa by
a staff member. It was found on the South African side of the Kalahari - just outside The Witsand Kalahari, specifically. It does NOT look stromatolitic and the fossil viewed side-on, when rotated, resembles a "Tully monster."
Size: left side fossil: 50mm W x 80mm L x 45mm D, Weight: about 1/2 lbs.
right side fossil: 45mm W X 60mm L X 30mm D, Weight: 0.8 lbs
