Match the following reptiles with their skull characteristics: Lizards | Classic diapsid skull Snakes | Robust skull with secondary palate Tuatara | Highly derived diapsid skull Crocodiles | Loss of lower temporal bar.
Understand the Problem
The question is asking to match different types of reptiles with their specific skull characteristics. It identifies four reptiles and describes their skull features, which is an exercise in understanding reptilian anatomy and evolution.
Answer
Lizards: Classic diapsid skull; Snakes: Highly derived diapsid skull; Tuatara: Highly derived diapsid skull; Crocodiles: Robust skull with secondary palate, loss of lower temporal bar.
Lizards have a classic diapsid skull, snakes have a highly derived diapsid skull, tuatara also have a highly derived diapsid skull, and crocodiles have a robust skull with a secondary palate and loss of the lower temporal bar.
Answer for screen readers
Lizards have a classic diapsid skull, snakes have a highly derived diapsid skull, tuatara also have a highly derived diapsid skull, and crocodiles have a robust skull with a secondary palate and loss of the lower temporal bar.
More Information
The skull structures of reptiles are characterized by the presence, absence, or modification of temporal openings. The classic diapsid condition features two temporal openings, while derived conditions may show modifications, such as losing bars, to suit ecological demands.
Tips
A common mistake is confusing derived diapsid conditions with other skull types such as synapsid or anapsid. Remember that diapsid modifications deal with temporal bars.
