"the days when the Chicxulub impact site was being identified as the main Cretaceous/Tertiary (K/T) event that the supporting evidence for the regional location was thick layers of ejecta at the K/T boundary found around the Caribbean."
I've always wondered about this...
Yeah, before they identified the crater structure in the Yucatan, they were sniffing around Cuba and Puerto Rico. Haiti has some thick K/T ejecta layers, too.
