Late Early Devonian Dacryoconarid Tentaculites, Northern Yukon Territory

Canadian Journal of Earth Sciences, 1972
The late Early Devonian succession in northern Yukon Territory contains a well-preserved dacryoconarid tentaculite fauna dominated by Turkestanella acuaria (Richter) in the upper part of the Road River Formation and T. acuaria and Nowakia parabarrandei Churkin and Carter in the overlying Michelle Formation. Based on the dacryoconarid tentaculite fauna

Chapter 3 Modelling late devonian extinction hypotheses

2005
Abstract Modelling the conditions of extinction hypotheses can lead to the discernment of the critical observations that must be made in order to definitively test those hypotheses. Models considered here are based upon the beginning ning assumption that the end-Frasnian biodiversity crisis was triggered in large part by pulses of global cooling ...

Insight into lingulid evolution from the Late Devonian

Alcheringa: An Australasian Journal of Palaeontology, 1977
Well preserved lingulids from near the base of the Mandagery Sandstone in the Late Devonian Hervey Group, N.S.W. are described as Apsilingula parkesensis gen. et sp. nov. The internal structures are better preserved than those of any previously described Palaeozoic lingulid and it has been possible to reconstruct the muscle system and to demonstrate a ...

Late Devonian, Permian and Triassic Phytoliths from Antarctica

Micropaleontology, 1999
This paper documents the discovery of phytoliths (siliceous plant fossils) from late Devonian, Permian and Triassic Beacon Supergroup strata at Mts. Crean and Feather in the Transantarctic Mountains, Antarctica. The five phytolith forms documented here are among the oldest phytoliths reported to date.
