Fissuravis ("fissure bird") is a genus of extinct bird from the Paleocene of Germany. A lithornithid, it was closely related to modern ratites, but it was a capable flyer.^[1]

Ecology

Hailing from the Walbeck Paleocene deposits, it is found amidst a rich avian fauna, which also included the gigantic Gastornis and the enigmatic ratite Remiornis.

Like most lithornithids, it was probably a very competent flyer, its coracoid remnants suggesting powerful flight musculature, and it likely engaged in a similar style of soaring flight to Lithornis and Pseudocrypturus.^[1]
