New Evidence Connects Dung Beetle Evolution to Dinosaurs

4 May 2016

Dr. Nicole Gunter, invertebrate zoology collections manager at The Cleveland Museum of Natural History, discusses research that uncovered an evolutionary connection between dinosaurs and dung beetles. The findings place the origin of dung beetles in the Lower Cretaceous period, with the first major diversification occurring in the middle of the Cretaceous.

A very rare fossil of a beetle that lived in the Netherlands 200 million years ago was found in a quarry in Winterswijk, according to a scientific publication in Paläontologische Zeitschrift written by paleontologists from Utrecht University,

From Paläontologische Zeitschrift:

New fossil insects from the Anisian (Lower to Middle Muschelkalk) from the Central European Basin (Germany and The Netherlands)

22 April 2017

Abstract

The Palaeozoic–Mesozoic transition is characterized not only by the most massive Phanerozoic mass extinction at the end of the Permian period, but also its extensive aftermath and a prolonged period of major biotal recovery during the succeeding Middle to Late Triassic.

Particularly, Anisian insect species from units of the Lower to Middle Muschelkalk from the Central European Basin are rare.

The Anisian is from 247.2 million years ago until 242 million years ago. So, older than the ‘200 million years ago’ of the Janene Pieters article.

The specimens described here originated from the Anisian Wellenkalk facies (Lower Muschelkalk), Vossenveld Formation of the Winterswijk quarry, The Netherlands, and from the orbicularis Member (lowermost Middle Muschelkalk, Anisian) of Esperstedt near Querfurt (Saxony-Anhalt).

Thus, the described insect remains from Winterwijk and Esperstedt expand our knowledge about Middle Triassic terrestrial arthropod communities and their palaeodiversity. A new species of Chauliodites (C. esperstedti sp. nov) is introduced.
