Wrong.
Deinosuchus (15 meters long, ~65 MYA, ate dinosaurs):
Stromatosuchus (12 meters long, ~65 MYA, was a filter-feeder for small fish like minnows)
Metriorhynchus (3 meters long, ~145 MYA, swam in the open ocean and ate fish)
These animals, only three of a vast number of crocodilians both extinct and extant, show *considerable* change ove rthe last 200 million years.
yeah, but your pics are all pics of RAPID breeding alligators, while he was talking about SLOW breeding alligators!
(i'm kidding)
"Wrong."
Incorrect. The species alive today have remained virtually unchanged for scores of millions of years...even though it has undergone prolific breeding over such vast amounts of time.
Nice try, though. Ya gets a cupie doll fur dat one.
