Siegfried Rein

from Wikipedia, the free encyclopedia

Siegfried Rein (* 1936 ) is a German paleontologist from Thuringia .

Life

Rein was a teacher, lives in Erfurt , where he works as a freelancer for the natural history museum and is responsible for the shell limestone collection.

He deals with the ammonites of the upper shell limestone ( ceratites ), their systematics and their paleobiology. Evidenced by statistical analyzes of a large number (in the three-digit range) of specimens within populations or biozones , he advocates a fundamental revision of the taxonomy and sees in the literature a procedure based only on morphological aspects, which leads to an incorrect attribution with many new ones Species and genera. He investigated this specifically with Ceratites nodosus , which migrated from the Tethys into the less favorable living conditions of the shallow Muschelkalke and had to adapt to different ecological conditions over time with a corresponding variety of forms, which are described in the literature as different species, but the pure ones Assigns type. He consistently distinguished between an E and P shape, which he interpreted as gender dimorphism. In contrast, Max Urlichs , who starts from the classic morphological species concept, came up with two lines of development in 2006.

Like the engineer and private paleontologist Klaus Ebel , he takes the view that ammonites cannot float freely in water (and only swim to a limited extent) and that they lived on the sea floor. He sees evidence for this in the fact that weight gain through constant settlement ( Epökie , relatively common in Ceratites in Muschelkalk) in the fossil material did not result in any visible compensation of the buoyancy through chamber gains (in contrast to Nautilus ).

In 1998 he received the Zittel Medal . He is active in the Trias-Verein Erfurt.

He also edited the writings of Friedrich Christian Lesser and published a biography about him.
