anapsid /əˈnapsɪd /noun ZoologyA reptile of a group characterized by a lack of temporal openings in the skull, including the turtles and their relatives and many early fossil forms.- Sometimes placed in a subclass Anapsida, though this taxon is now often not recognized.
All members of the group called the Reptilia, except for the anapsids (turtles and their ilk), and a few extinct groups, are diapsids....- If anything, the synapsids seem more closely related to anapsids than diapsids.
- Today, only one group of anapsids remains (Chelonia - the turtles), which truly could be called an evolutionary success story.
Origin 1930s: from modern Latin Anapsida, from Greek an- 'without' + apsis, apsid- 'arch'. |
