On Liassic holothurian and ostracod assemblages from the Danish Embayment

Research output: Chapter in Book/Report/Conference proceeding › Chapter in book › Research

Abstract

Liassic holothurian sclerites from the Danish Embayment are studied and referred to four morphospecies.

On the basis of quantitative analysis of the holothurian and the ostracod assemblages, which are compared with previous studies of the sediments (Larsen 1966), ecological aspects of the Ogmoconchella aspinata Assemblage Zone Michelsen 1971 (Lias Alpha) are outlined. Regional differences of the environment are demonstrated. The Rødby No. 1 boring is situated in a marginal position with an environment characterized by quiet, marine deposits interstratified by deltaic sediments. The Gassum No. 1, Horsens No. 1, and Vedsted No. 1 borings, situated more centrally in the basin, present a quiet sedimentation in a pure marine environment.
