“…() used a single profile of the sparse local seismic reflection data to support the crater hypothesis. While seismic reflection data can identify large impact structures (Morgan et al., ; Osinski & Spray, ; Poag, , ; Poag, Hutchinson, Colman, & Lee, ; Scott & Hajnal, ; Stewart & Allen, ; Wu, Milkereit, & Boerner, ), we argue that the seismic data they presented do not corroborate the crater hypothesis. Typically, impact craters identified on seismic data have the following features (French, ; French & Koeberl, ), none of which are convincingly seen in the seismic data: - modest downward and inward displacements of the rocks at the crater margin;
- a complex ring fault system;
- structural disruption in a central zone, with incoherent seismic reflectors and evidence of preserved and continuous reflectors at depth.
