- Which of the following taxa of fish shared most direct common ancestry with the group of animals that evolved into the terrestrial tetrapods? -Subclass Elasmobranchii -Class Neopterygii -Subclass Sarcopterygii -Class Actinopterygii -Class ChondrichthyesPair the words with the right description: Mammalia , Testudines, Rhynchocephalia, Amniota Tetrapoda,Cryptodira, Reptilia ,Squamata, Crocodylia, Pleurodira, Lepidosauria,Archosauria,Crocodiles, Anura The oldest lineage of extant reptiles. This clade is the sister taxon to reptiles. Adults are terrestrial and nocturnal, while the young are diurnal. Larval forms of most species are herbivorous while adults are insectivorous/carnivorous. The closest living relatives of avian reptiles. They are known as the "side necked" turtles. Have elongate, tapering snouts and, with the mouth closed, the 4th tooth on the lower jaw is visible. Most diverse and speciose clade of reptiles. Adults of this taxon are known to be cannibalistic on younger individuals. Possess teeth set in bony sockets and replace teeth throughout their lives. Males in this taxon have paired copulatory organs and movable quadrate bone in the skull.
