The dinosaurs were wiped out 65 million years ago by at least two space impacts, rather than a single strike, a new study suggests. Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs. Now evidence for a second impact in Ukraine has been uncovered. The Boltysh Crater in Ukraine was first reported in 2002. However, until now it was uncertain exactly how the timing of this event related to the Chicxulub impact. Read more
Boltysh impact crater drill core samples arrive in UK One hundred and two core boxes containing over 400 m of core from the Bolytsh impact crater in the Ukraine have arrived in Aberdeen as part of the NERC funded project into the environmental effects that resulted from this 65 million year old impact crater. CEPSAR scientists Jon Watson, Simon Kelley and Iain Gilmour joined their University of Aberdeen colleague Dave Jolley for an exciting day doing an initial sampling of the core.
The Boltysh Crater is an impact crater in the Kirovohrad Oblast province of Ukraine. The crater is 24 km in diameter and its age of 65.17 ± 0.64 million years, based on argon dating techniques, is within error of that of Chicxulub Crater in Mexico, and the KT boundary.
