Sauropsids
by Thomas M.
The sauropsid node is one of the most enigmatic evolutionary traits. Technically speaking, sauropsids have a pair of openings in the palate. While these holes could allow blood vessels and nerves to pass through, the designated purpose for them is unknown. Sauropsids include dinosaurs and reptiles, including the turtle and the crocodile.
