2 extinct reptiles 100mn yrs apart found to be similar
A 220 million-year-old reptile fossil recently unearthed in Texas has been found to possess strong resemblances to a reptile, 'pachycephalosaur', that evolved 100 million years later. Both had enlarged domes of solid bone behind their heads above the brain. The recently found 'Triopticus Primus' fossil has a large eye socket-like pit in the skull, raising speculations of a 'third eye'.
