From Wikipedia, the free encyclopedia
- Robertia as described by Saaristo in 2006 is the (invalid) new genus name for the spider Theridion braueri, described by Simon in 1898.
Robertia broomiana was a small, primitive dicynodont; among the earlier members of the group. It is known from the Tapinocephalus assemblage zone of the South African Karoo, and was about 20 cm in length. It is characterised by a moderately wide skull roof, small postcanine teeth, and the palatine bone in the roof of the mouth not as reduced as in its more successful relative Diictodon. Immediately in front of the tusk-like canines on the upper jaw is a notch, which would presumably hold tough plant matter like stems and twigs before these were severed by the horny beak.
