Definition of anapsid in English:

anapsid

nounəˈnapsɪdəˈnapsəd

Zoology

A 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.
〔动〕无孔型
Sometimes placed in a subclass Anapsida, though this taxon is now often not recognized
Example sentencesExamples
- All members of the group called the Reptilia, except for the anapsids (turtles and their ilk), and a few extinct groups, are diapsids.
- The relationships of more basal anapsids are not firmly established, but millerettids apparently appeared first.
- Today, only one group of anapsids remains (Chelonia - the turtles), which truly could be called an evolutionary success story.
- If anything, the synapsids seem more closely related to anapsids than diapsids.
- Therefore, a long hiatus exists in the fossil record of anapsids.

Origin

1930s: from modern Latin Anapsida, from Greek an- 'without' + apsis, apsid- 'arch'.
