World's Largest Worm Lizard Fossil Unearthed
Researchers have discovered the largest known worm lizard species, Terastiodontosaurus marcelosanchezi, in Tunisia. This 50-million-year-old species, with a skull over five centimeters long, likely fed on snails using its powerful jaws and specialized tooth enamel. Unlike modern worm lizards that live underground, this ancient species may have also lived on the surface due to its size. The discovery highlights the evolutionary consistency of snail-eating habits in worm lizards over millions of years.
