Pseudasturides

Pseudasturides is an extinct genus of halcyornithid bird from the Middle Eocene Messel pit in Hesse, Germany, and possibly the Isle of Sheppey, United Kingdom.

The referred specimens differ slightly in size and morphology compared to the holotype, and their assignment was tentative.

The specific ephitet macrocephalus is from Greek makrocephalos, meaning large-headed, in reference to the proprtionally large head found in the species.

[1][2] Further specimens from the Isle of Sheppey in England have been tentatively assigned to Pseudasturides macrocephalus, including a partial skeleton with skull fragments, as well as the distal part of a tarsometatarsus.

The cranium is rounded, and the beak is robust and short, measuring approximately one-third of the length of the skull.
