Chelidae - correct answer ✔✔ non-Cryptodira’s from the southern hemisphere
Chelydridae - correct answer ✔✔ nocturnal, sharp-beaked predators

Gekkota - correct answer ✔✔ synapomorphy: no eyelids or rod cells in the retina
Serpentes - correct answer ✔✔ synapomorphy: obligate limblessness

Jaw morphology with their proper feeding mode in squamates: absence of upper and lower
skull arches - correct answer ✔✔ Most flexible gape; capable of jaw dislocation to consume
large prey
secondarily fused and exaggerated skull bones - correct answer ✔✔ most limited gape for
feeding, thus eat smallest-sized prey

ancient condition - upper and lower arches present - correct answer ✔✔ 2nd most limited gape
for feeding

A.Serpentes
B.Lacertoidea
C.Anguimorpha
D.Rhynchocephalia
E.Amphisbaenia - correct answer ✔✔ C.Anguimorpha
