Question

Fossil remains of Archaeopteryx were recovered from the rocks of? Triassic period Jurassic period Palaeozoic era Pliocene epoch

Answer 1

The Archaeopteryx is from the Upper Jurassic estimated to be 150 million years ago.

Explanation:

The Archaeopteryx is not ancestral of any group of modern birds. (Larry Martin. The relationship of Archaeopteryx to Other Birds
Extinct Bird like Dinosaurs date from about 120 million years.
The extinct bird like dinosaurs can not be the ancestors to the Archaeopteryx because an organism can not be older than its ancestors.

Another bird like fossil the Bambiraptor was found in the Upper Cretaceous rocks about 75 million years old. This fossil was thought to be more primitive a bird than the Archaeopteryx which is much older.

the Archaeopteryx is still a mysterious fossil. The Archaeopteryx appears to be somewhat between reptiles and birds. but it is older than any other fossils that are thought to considered to be transitional.
