What is "teurisci"

Teurisci was a Dacian tribe at the time of Ptolemy (140 AD). They are considered originally Celts, a branch of the Celtic Taurisci ( Noricum), who moved to Upper Tisza. However, the archaeology shows that Celts have been absorbed by Dacians, at some extent both creating a Celto-Dacian cultural horizon in the upper Tisza.
