A CT scan of an ancient marine reptile that was entombed while pregnant has revealed a huge surprise — there were two fetuses inside her fossilized remains.
"Twins! She has another baby," Judith Pardo-Pérez, a paleontologist at the University of Magallanes in Chile who first discovered the fossil in 2009, told Live Science, adding that she plans to release more details of this discovery in a forthcoming research paper.
