Synchrony between the Central Atlantic magmatic province and the Triassic-Jurassic mass-extinction event? Comment.

Based on multidisciplinary palynological, magnetostratigraphic, geochemical, and geocrhonological data a significant part of CAMP lava flows predated the T-J boundary, and therefore the CAMP event may have contributed to the end-Triassic biotic turnover. Several open questions on the T-J boundary and on CAMP highlighted by the published special volume of this journal (Hesselbo et al., 2007) have been constrained by our high quality geochronologic data for the two events and by combined and complete bio- and magnetostratigraphic data for T-J sedimentary basins, which presently on both sides of the Central Atlantic are limited mostly to strata which occur below the first CAMP lava flows.
