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
