Not sure but I believe there was a large one off the coast of Virginia also…

The Chesapeake Bay impact crater

Given that the seas off the coast of eastern North America, Antarctica, Argentina, and North Africa but also the shallow seas of Europe boasted mosasaurs, sharks, ammonites, plesiosaurs, and other marine organisms during the late Campanian-Maastricthian, the discovery of the Nadir Crater potentially could potentially answer questions about the rate which the K-Pg extinction event wiped out many shark and marine reptile groups in the Atlantic coastal plain and shallow seas off North Africa, Patagonia, Antarctica, and Europe. Since the asteroid impact off the Yucatan Peninsula is often seen as the final event of the K-Pg mass extinction, the Nadir Crater may suggest that non-avian dinosaurs, pterosaurs, plesiosaurs, mosasaurs, and some sharks were wiped by not one, but two asteroid impacts (volcanic eruptions in India happened not too long before the asteroid impacts).
