They were a very small family of slim and long-winged soaring pterosaurs that trapped fish between their thin, needle-like teeth.

Boreopterus
Once thought to be an ornithocheirid, Boreopterus actually belongs to the Boreopteridae pterosaur family along with fellow weirdos Guidraco and Zhenyuanopterus.
Guidraco
Guidraco is known from the remains of only one partial skeleton found in Liaoning Province, China.
Hasandong Boreopterid
The Hasandong pterosaur was a member of the boreopterids, a group with vertical needle-like teeth that probably fed on fish and small vertebrates.
Zhenyuanopterus
Zhenyuanopterus may have used its long, delicate teeth to ambush small prey in the water, or for filter-feeding.
