Abstract: Abstract Sprayet al.1 postulate that five widely dispersed terrestrial impact structures with very similar geological age estimates (about 214 million years ago, in the Late Triassic epoch) are evidence of a multiple impact event. Most notably, the three largest impact structures, Saint Martin in western Canada (∼40 km diameter), Manicouagan in eastern Canada (∼100 km diameter), and Rochechouart in France (∼25 km diameter), plot at virtually the same palaeolatitude in a continental reconstruction. Spray et al. suggest that this apparent crater chain was produced within hours as a series of coaxial projectiles collided in rapid succession with the rotating planet Earth, and drew analogies to the recent collision sequence of fragmented comet Shoemaker-Levy 9 with Jupiter.
