is much on-going uncertainty about exactly what kind of creatures
Banffia actually were, and differing opinions
place them either
within the Arthropoda, Vetulicolia or Urochordata. At up to ten
centimetres long, Banffia were quite large when
compared to many of
the creatures of the Burgess Shale. The body is very interesting
because in life it would have been twisted in a clockwise spiral. The
body can be equally divided into anterior (front) and posterior
(rear) sections, the posterior section is also segmented. There
are no gills, and an endostyle is also lacking, and aside from what
appear to be some antennae, there are no appendages. It is the lack
of these diagnostic features which makes it difficult to be certain as
to exactly what Banffia were.
Possible close relatives of Banffia were Skeemella.
