Analysis of
fossil data has
shown that
turtles are
likely diapsid reptiles, most

modern paleontologists believe that the
Testudines are
descended from
diapsid reptiles that lost
their temporal fenestrae. More
recent morphological...

found turtles to
either be
descendants of parareptiles, early-diverging
diapsids outside of Sauria, or
close relatives of
lepidosaurs within the
clade Ankylopoda...

diapsids,
dinosaurs ancestrally had two
pairs of
Infratemporal fenestrae (openings in the
skull behind the eyes), and as
