Description

Sinamia liaoningensis

change

Sinamia liaoningensis is a very large fish and has a much more podgy body form than the other species of the genus but still resembles the bowfin.

Sinamia kukurihime

change

Sinamia kukurihime is very similar to the modern-day bowfin. A pyriform-shaped gular has been described for two isolated ossifications of Sinamia kukurihime, whose outline resembles that of K. phattharajani, except for the smooth posterior margin of the first.
