Preferred Label : prefrontal bone;
Uberon definition : A bone separating the lacrimal and frontal bones in many tetrapod skulls;
Uberon broad term : prefrontal;
Uberon Taxon note : It first evolved in the sarcopterygian clade Rhipidistia, which includes lungfish
and the Tetrapodomorpha. The prefrontal is found in most modern and extinct lungfish,
amphibians and reptiles. It is very small, fused to the frontals or lost in many groups
of coelurosaurian theropod dinosaurs and is completely absent in their modern descendants,
the birds. The prefrontal was also lost in early mammaliaforms and so is not present
in modern mammals either;
