Rząd Westergaardodinida Lindström, 1970

Opis

Distinct from other conodonts in the structure of elements of the oral apparatus. The elements started their growth as minute rod s lacking any basal cavity, with the crown tissue sec reted
from all sides. Sub sequent secretion of the crown tissue was restricted to the basal part s of the element surface and to the margin of the basal cavity. The crown tissue contained originally a lot of organic matter, the basal filling tissue, if present, is weakly mineralized (see ANDRES 1988).
