Parabohaiornis is an
Discovery
Parabohaiornis was first described and named by Min Wang, Zhong-He Zhou, Jingmai K. O'Connor and Nikita V. Zelenkov in
paleontologist Prof. Larry Dean Martin, for his contributions to the study of the evolution of birds.[1]
Parabohaiornis is known from the
million years ago.[1]
Description
Parabohaiornis differs from all other known
metatarsal of 0.92–0.99, in comparison to 1.06 in Longusunguis, 0.79 in Sulcavis, 0.66 in Zhouornis and an estimated ratio of 0.82 in Bohaiornis. Finally, while in other bohaiornthids the proximal phalanx is more than 80% the length of the penultimate phalanx of the fourth digit, in Parabohaiornis it is much shorter (less than 70%). The referred specimen of Parabohaiornis is indistinguishable from the holotype in morphology, possessing all postcranial traits that distinguish this genus from other bohaiornithids. Both specimen came from subadult individuals, the referred being more mature than the holotype, as evident by the absence or degree of fusion in some compound bones, such as the carpometacarpus, tibiotarsus and tarsometatarsus.[1]
Phylogeny
The
bohaiornithid, closely related to Bohaiornis whose specimens were collected at a nearby locality, also near the Lamadong Town. The cladogram below shows the phylogenetic position of Parabohaiornis among the Enantiornithes following this analysis.[1]
