Question

when scientists studied geological columns from different parts of the world, they discovered something interesting: the fossils of dinosaurs and many groups of reptiles and marine invertebrates disappeared at the top of the mesozoic section. what is the most likely explanation of this evidence? responses

Answer 1

The most likely explanation for the disappearance of the fossils of dinosaurs and many groups of reptiles and marine invertebrates at the top of the Mesozoic section is that they became extinct at the end of the Mesozoic era, possibly as a result of a catastrophic event such as an asteroid impact or volcanic activity. This event is commonly referred to as the Cretaceous-Paleogene extinction event.
