Pelycosaur (/ˈpɛlɪkəˌsɔːr/ PEL-ih-kə-sor) is an
older term for
basal or
primitive Late
Paleozoic synapsids,
excluding the
therapsids and
their descendants...
- systematics, and non-therapsid
synapsids were also
referred to as
pelycosaurs or
pelycosaur-grade synapsids.
These paraphyletic terms have now
fallen out...

ancestor (a

synapsids which are not therapsids). The
therapsid takeover from
pelycosaurs took place...
- (Cisuralian) saw a
major faunal turnover, with most
lineages of
primitive "
pelycosaur"
synapsids becoming extinct,
being replaced by more
advanced therapsids...

Varanopidae vanishes from the

secondary palate,

their pelycosaur ancestors,
