Tamga is an extinct animal genus of the Ediacarium , which is believed to belongto the Proarticulata .
etymology
The generic name Tamga is derived from the Turkish word of the same name , which means seal or brand . The species name hamulifera (carrying hook) is a Krasis compound of the Latin words hamulus (small hook) and ferre (to carry).
Initial description
Tamga was first scientifically described in 2007 by Andrei Yuryevich Ivanzov .
Occurrence
Tamga hamulifera fossils come from Precambrian strata on the White Sea coast in northern Russia .
description
The very small, only 3 to 5 millimeters long, disc-shaped fossil has seven, hook-like isomers that are arranged in a star shape along the outer zone. Tanga hamulifera probably belonged to the tribe of proarticulata as it is very strong with its hook-shaped isomers and in its general, physical appearance Praecambridium sigillum similar. The flattened body with its compact group of outstanding isomers in the center, which is surrounded by an undivided edge area, also shows a certain relationship with Onega stepanovi .
Tamga fossils are possibly sclerites - for example, sclerites of the Palaeoscolecida show a very similar disc shape with a ring or rows of tubercles in the middle. However, this contradicts the different sizes of tamga. In addition, no sclerites have been diagnosed in fossil communities of the Ediacarian so far.
