Scientists concluded that some fossilized foot marks left by a big meat-eater on a lake bed in northern Spain 125 million years ago provide strong evidence that at least some dinosaurs were good swimmers.
Dinosaurs ruled the land from about 230 million years ago to 65 million years ago. But how they did in the water has been less clear.
There were numerous huge, fully marine reptiles living at the same time, but they were not dinosaurs and in fact were only very distantly related to them.
Scientists have been seeking evidence that dinosaurs — like today’s large mammals such as elephants and tigers — were capable of swimming when circumstances demanded, like hunting in wet ecosystems, crossing rivers or escaping floods.
Previously discovered fossils showed swimming tracks apparently left by other dinosaurs such as sauropods — long-necked animals like Diplodocus — and duckbilled dinosaurs.
The new tracks provided the first definitive evidence of an active swimming behavior in dinosaurs and are the best record of swimming by theropods, researchers said.
verey cool not
I agree. Evolution is not cool, and so untrue.
Evolution has no proof at all why believe it?
Wow finally some people who think the same as I do! Ya evolution is so stupid I don’t understand how anyone could belive it.
i agree
evolution has no proof
if so, you bring a better explanation, this si the best theory so far. :-}
Sorry, if I was too blunt. Hope you accept my apologies.
How could anybody belive evolution????
ok kosherscout I accept your challenge if evolution is true you want to know what the chances were? 1 out of 999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999 want to know what the chances for creation are? 1 out of 1. Now I ask you wiche is more likly? Oh and just a note evolution is just a thory.
i do nt think they were dinos
the THEORY of evolution gos against the 2nd LAW of thermodynamics (laws are proven
theory’s are NOT)
there were sharks like cretoxeyrina and megladon
