Re: Big Dinosaur Prints Found



"Trace fossils are the only fossil, with the exception of an immutably autochthonous benthonic organism, that you can look at and know with certainty that the organism that left it was actually present on the bedding plane or bounding surface that you are now observing."

A few years back a dinosaur track was found on Long Island which was clearly brought in from Connecticut or elsewhere in the Conn. River Valley. Yes, the dinosaur was clearly present on the observed bedding plane, but the bedding plane was transported - a nightmare of reworking. Extinct Mesozoic dinosaurs can still migrate :)
