The Academy of Natural Sciences in Philadelphia has confirmed Paul Kovalski's suspicions about his latest find - that a 3-by-3-inch brown disc laying on the banks of Big Brook is in fact from a dinosaur.
The Marlboro dentist says the innocuous-looking find - discovered in December a few miles inland from the central Jersey shore - is likely a leg section from a duckbilled dinosaur called a hadrosaur.
The bone is a rare find in New Jersey, Kovalski says, even though the Big Brook area is billed as one of the top fossil-finding sites in the nation.
