Overview

Analysis uncovers ichnofossil diversity in ancient sea bottoms, suggesting sedimentary dynamics.

Key Points

  • The research aims to analyze the ichnologic characteristics of the Cranbrook Lagerstätte from the early Cambrian period.
  • Conducted a systematic field investigation of a 2.65 m interval in the Cranbrook Lagerstätte.
  • Identified and described 12 ichnotaxa and three types of trace fossils in open nomenclature.
  • Examined ichnocoenoses formed by different trace fossil assemblages.
  • Identified abundant ichnofossils, including Helminthoidichnites tenuis and Diplocraterion isp.
  • Described two main ichnocoenoses related to distinct environments: one for shallow burrows and another for U-shaped burrows.
  • Trace fossils suggest colonization by surficial and shallow-tier infauna during brief periods between sediment flows.
