Key Points

  • Fossil fish swim tracks were identified in Upper Cretaceous sediments, revealing ancient aquatic behaviors.
  • The study details ichnofossils found along the Black Sea coast, shedding light on past ecosystems.
  • Analysis of sediment layers provides insights into the paleogeography of the Late Cretaceous and Early Paleogene periods.
  • Findings may enhance understanding of ancient marine environments, highlighting biodiversity during this era.

Abstract

This paper describes fossil fish swim tracks in soft sediments discovered in the Upper Cretaceous deposits of the Black Sea coast of the Caucasus (Khosta River basin, Krasnodar Region). The author’s interpretation of the Late Cretaceous–Early Paleogene paleogeography of the study region are discussed.
