Computer Model of Romundia Scull (image) Uppsala University Caption This is a computer model based on scan data from the 2 cm long Romundia scull. Gold/orange and grey represents different types of bone. The brain cavity and nerves are shown in yellow, veins in blue, arteries in red. Romundia has separate left and right nostrils, but they sit far back, behind an upper lip like that of a jawless vertebrate.
