Vetulicolians from the Lower Cambrian Sirius Passet Lagerstatte, North Greenland, and the polarity of morphological characters in basal deuterostomes

Abstract:

Abstract: Vetulicolians are problematic Cambrian fossils with a debated phylogenetic history. Here, we describe two vetulicolian specimens from the Lower Cambrian Sirius Passet locality in North Greenland. One of the specimens is assigned to Ooedigera peeli gen. et sp. nov, whereas the other is retained under open nomenclature. The mode of tail flexibility has been debated in the literature, and we argue here that the tail normally flexed laterally to generate power strokes rather than dorsov...
