New Mastodon Discovery in Western New York

Scientists from the Paleontological Research Institution (PRI) and Cornell University are recovering the bones of a mastodon from a pond in rural Wyoming County, between Rochester and Buffalo. The bones were found by Robert Moffett of North Java, NY when he had a fishing pond dug on his property more than a year ago.

Found thus far are several fragments of skull, several ribs, a toe bone, a fragment of tusk, and one well-preserved tooth. It is not clear how many more bones may be buried at the site. Although it is difficult to draw firm conclusions based on so few bones, the skeleton appears to be notably smaller than most other mastodons found in the region. This may indicate that it was a juvenile or, perhaps, a female, but this is speculative at this point.

The diameter of the North Java tusk is only about half the size of the Hyde Park Mastodon. The far (distal) end of the North Java tusk is broken, but if it were intact, it would also be shorter than the Hyde Park tusk.

No bones have yet been found in place in the earth; all were discovered in the piles of peat and clay that were excavated from Moffett's pond. The scientists will be sieving all of these piles to search for more bones, as well as expanding the pond to see if any can be found in position. Mastodons in New York State are frequently preserved in glacial ponds called kettles. It is too early to know if this was a kettle pond, but it is very likely that the bones are buried in glacial sediment of some kind. The age of the skeleton has not been determined; similar finds in New York State have been dated at between 11,000 and 15,000 years old.
