Question

Quizplus · Accepted Answer

Snakes and lizards both have a highly mobile skull and jaw that aids in feeding, known as a kinetic skull. This is a shared characteristic that distinguishes them from other groups of reptiles and is a key factor in their classification within the order Squamata. Option A is incorrect as Archosauria is a different order of reptiles. Option C is a feature found only in lizards and not in all members of the Squamata. Option D refers to a specific type of tooth attachment and is not a defining characteristic of the Squamata order.
