Huge skulls clues to snake evolution
"New fossils found in Australia tell us that enormous snakes evolved from predatory lizards like goannas, scientists say.
Palaeontologist Dr John Scanlon describes the well-preserved 25 to 20 million-year old snake skulls from the Riversleigh World Heritage site, in today's issue of the journal Nature.
'There's been quite a bit of controversy about what sort of lizards snakes evolved from,' says Scanlon, of the Riversleigh Fossils Centre in Mount Isa (Australia)." [Evolution News]
