Question

The zenith of iguanodontid diversity was during the ____________.

A. Late Jurassic
B. Late Cretaceous
C. Early-Middle Jurassic
D. Early-Middle Cretaceous

Answer 1

Option B). The peak of iguanodontid diversity occurred during the Late Cretaceous period, the last portion of the Mesozoic Era known as the Age of Reptiles.

Step-by-step explanation:

The Late Cretaceous represents the pinnacle of iguanodontid diversity. After the mass extinction at the end of the Jurassic Period, which allowed dinosaurs to flourish, this period of geological history saw the peak of dinosaur distribution and size. The Cretaceous Period, which lasted from roughly 145 to 66 million years ago, was the end of the Mesozoic Era, also known as the Age of Reptiles. It ended with a major mass extinction event. Hence, Option B) is the correct answer.
