Research throughout the Caribbean suggests that the geophysical anomalies in the Yucatan first noted by Penfield and Camargo (1981) and called the Chicxulub crater could be the site of the impact purported to have caused the K/T extinctions. A semicircular ring of sink holes, known locally as cenotes, which correlates with the geophysical anomalies has been identified, and it is argued that the origin of the cenote ring is related to postimpact subsidence of the Chicxulub crater rim. If there… Expand
Surficial geology of the Chicxulub impact crater, Yucatan, Mexico
TLDR
The Cenote Ring provides the most accurate position of the Chicxulub crater's center, and the associated faults, fractures, and stratigraphy indicate that the crater may be ∼240 km in diameter. Expand

Chicxulub impact tsunami megaripples in the subsurface of Louisiana: Imaged in petroleum industry seismic data
Abstract Large-scale megaripples have been recognized in a petroleum industry 3D seismic horizon near the Cretaceous/Paleogene (K-Pg) boundary. These features occur at the top of theExpand

Volcanism around K/T boundary time – its role in an impact scenario for K/T extinction events
Abstract A widespread debate on the Cretaceous/Tertiary (K/T) boundary (65 ± 1 Ma) extinctions has largely revolved around an impact or a volcanic cause. Evidence for both events is strengthened byExpand

Extraterrestrial Cause for the Cretaceous-Tertiary Extinction
TLDR
A hypothesis is suggested which accounts for the extinctions and the iridium observations, and the chemical composition of the boundary clay, which is thought to come from the stratospheric dust, is markedly different from that of clay mixed with the Cretaceous and Tertiary limestones, which are chemically similar to each other.
