Just to put my 2 cents worth in, I'd like to just summarise an answer to the question of this thread for Creationists.
Question :
"Did dinosaurs live with man?".
The way most creationists and general members of the public will translate this question in their minds would probably be : "
Did modern humans (H. sapiens) live during the Mesozoic era? (the era that was
dominated by the dinosaurs - that is occupying most of the tetrapod ecological niches of the time.
The short answer to this is
No, modern humans or even hominims, did not live at the same time as dinosaurs during the Mesozoic.
However, a qualification should be added :
It is generally accepted by most biologists, ornithologists and palaeontologists today that birds (called
Avialae in scientific parlance) are a sub-group within the clade
Dinosauria which are all grouped under the Class
Reptilia.
Given that modern birds (
Avialae) are considered to be Dinosaurs, then we can say that dinosaurs have been living with H. sapiens (modern humans) since humans originated in Africa approximately 200,000 years ago.
