Lossinia is an extinct animal species of uncertain taxonomic classification that lived in the Ediacarium . It is likely to be classified in the stem of the Proarticulata .
description
Lossinia fossils are small, oval in shape. Their length varies between 3.2 and 8.4 millimeters, their width between 1.8 and 4.7 millimeters. The body can be divided into a conspicuous, semicircular head shield area and an elongated trunk, divided into segments. The entire head area and the central axis area of the trunk are littered with small tubercles , which hide the underlying segmentation of the fossil near the axis. As with other proarticulata it should also reflected in the segments Lossinias to isomers act. The characteristic head shield covered with tubercles marks small representatives of the proarticulata such as Onega and Archaeaspinus as well as the completely unsegmented and completely covered with tubercle taxon Armillifera .
Occurrence
The fossils of Lossinia come from the Verchowka Formation and from the Jorga Formation of the northern Russian Ediacarium ( Vendiums ).
Taxonomy
Lossinia and Lossinia lissetskii were scientifically described for the first time in 2007 by Andrei Jurjewitsch Iwanzow . The generic name Lossinia is derived from the Lossinoje swamp located near the type locality (Simni Bereg, Russian White Sea coast , Arkhangelsk region ). The Russian word Lossinoje comes from лось , which means moose . The species name lissetskii honors the former caretaker of the Zimnegorsky lighthouse Valery S. Lissezki.
