An endemic ichnoassemblage from Tertiary paleolake in SE Iceland

In Þórisdalur valley in southeastern Iceland, a small relict of unique sedimentary body was identified. It probably represents a remnant of a deep, tectonically arranged paleolake (Late Miocene, 8–9 Ma), filled with volcaniclastic material from the nearby active volcanic centers. Trace fossils of the newly described endemic ichnoassemblage (e.g., Thorichnus ramosus igen. et isp. nov., T. corniculatus igen. et isp. nov., Mammillichnis jakubi isp. nov., Vatnaspor jachymi igen. et isp. nov.) were identified in the sedimentary section. The results of the study, actively participated by Assoc. Prof. RNDr. Lukáš Krmíček, Ph.D. of the Institute of Geology of the Czech Academy of Sciences, are currently published in Palaeogeography, Palaeoclimatology, Palaeoecology.
