The ichnological record across the Cretaceous/Tertiary boundary in turbiditic sediments at Uzgrun (Moravia, Czech Republic)

, : The ichnological record across the Cretaceous/Tertiary boundary in turbiditic sediments at Uzgrun (Moravia, Czech Republic). Geologica Carpathica 56(1): 57-65

The deep-sea, distal turbiditic deposits at Uzgrun have recorded no significant change of trace fossil diversity and ichnofabrics across the Cretaceous/Tertiary (K/T) boundary interval. There is no evidence of any ecological catastrophe that can be related to the K/T event. The trace fossil association is rather poor in diversity. This can be related to a general oligotrophy and poor preservation potential. The producers of the discussed trace fossils, dominated by Chondrites intricatus (Brongniart), Chondrites targionii (Brongniart), Ophiomorpha annulata (Ksiazkiewicz), Ophiomorpha rudis (Ksiazkiewicz), Palaeophycus tubularis Hall, Planolites isp., Phycosiphon incertum Fischer-Ooster, Thalassinoides isp. and Trichichnus isp. lived in a habitat, which had not been influenced by the event.
