Benthic foraminiferal turnover across the Cretaceous / Paleogene boundary at Agost ( southeastern Spain ) : paleoenvironmental inferences

  title={Benthic foraminiferal turnover across the Cretaceous / Paleogene boundary at Agost ( southeastern Spain ) : paleoenvironmental inferences},
  author={Laia Alegret and Eustoquio Molina and Ellen Thomas},
We studied Upper Cretaceous and Lower Paleogene benthic foraminifera from the Agost section (southeastern Spain) to infer paleobathymetrical changes and paleoenvironmental turnover across the Cretaceous/Paleogene (K/P) transition. Benthic foraminifera indicate uppermost bathyal depths at Agost during the Abathomphalus mayaroensis Biochron (from about 400 kyr before the K/P boundary) through the early Plummerita hantkeninoides Biochron (about 120^150 kyr before that boundary). The depth… CONTINUE READING
