Rhamphorhynchus muensteri (Wingset) Lyrics

A vane like a rhombus or a triangle
in the guise of the one of the Devil
used as a helm, to navigate the skies
nocturnal according to its scleral rings

needle like teeth, angled forward
curved, sharp beaklike tip
sexual dimorphism (in)conclusive:
wingspan, wingset, membrane muscles
in the ratio of skull to humerus length

fish and cephalopod remains found
frequently inside its stomachal contents
as well as a multitude of coprolites
a fossil limestone slab tells stories
of a Leptolepides in the throat

the osseous labyrinth gives balance
it holds its head in a parallel orientation
