Approximately 35,000,000 BC: Chesapeake Bay is struck by a comet possibly as large as three miles in diameter; a similar impact happens at Popigai, northern Siberia; 100,000 years of cooler than normal climate burdens the world in the aftermath

The Exmore Boulder Bed along the north through central eastern North American coast appears to be debris left from a cosmic impact roughly 35.5 million years BC, struck upon the continental shelf off New Jersey. This impact may represent a different event from that of Chesapeake Bay-- however, the close proximity in both location and time seems to indicate otherwise.

-- GIANT IMPACT-WAVE DEPOSIT ALONG U.S. EAST COAST From Science Frontiers Digest of Scientific Anomalies ["http://www.knowledge.co.uk/frontiers/"] #87, MAY-JUN 1993 by William R. Corliss, citing C.

Two major meteorite impacts, one following relatively closely after the other (perhaps separated by only 10,000 to 20,000 years), around 35 million BC in the vicinity of Chesapeake Bay USAmerica and Popigai of northern Siberia, caused a long term cooling of the world for around 100,000 years.
The meteorites may have each been around several km in diameter.
Some forms of sea life thrived at the lower temperatures incurred by the collisions. The lengthy period of cooling, which seems far too long to be accounted for solely by the dust of impact, may have been the result of global glaciation triggered by the initial cooling from the impacts.
