Despite extensive discoveries across the globe over the past two centuries, little phylogenetic work has been done on the Hesperornithiformes. Spanning the late Early to Late Cretaceous, hesperornithiforms are one of the most diverse groups of Mesozoic birds in terms of both their geographical distribution and the wide differences in body size and diving specializations. This study presents the first phylogenetic analysis of the Hesperornithiformes that includes a majority of the described taxa…

Anatomy of Parahesperornis: Evolutionary Mosaicism in the Cretaceous Hesperornithiformes (Aves)
The Hesperornithiformes constitute the first known avian lineage to secondarily lose flight in exchange for the evolution of a highly derived foot-propelled diving lifestyle, thus representing the…
Identification of a New Hesperornithiform from the Cretaceous Niobrara Chalk and Implications for Ecologic Diversity among Early Diving Birds
TLDR
Diversity in Hesperornithiforms that existed in the Late Cretaceous Western Interior Seaway points to the existence of a complex ecosystem, perhaps with a high degree of niche partitioning, as indicated by the varying degrees of diving specializations among these birds.
The Hesperornithiformes: A Review of the Diversity, Distribution, and Ecology of the Earliest Diving Birds
The Hesperornithiformes (sometimes referred to as Hesperornithes) are the first known birds to have adapted to a fully aquatic lifestyle, appearing in the fossil record as flightless, foot-propelled…
The oldest Asian hesperornithiform from the Upper Cretaceous of Japan, and the phylogenetic reassessment of Hesperornithiformes
TLDR
Chupkaornis has a unique combination of characters: finger-like projected tibiofibular crest of femur, deep, emarginated lateral excavation with a sharply defined edge of the ventral margin of the thoracic vertebrae, and the heterocoelous articular surface of the abdomen.

New finds of hesperornithids in the European Russia, with comments on the systematics of Eurasian Hesperornithidae
TLDR
The validity of Hesperornis rossicus is adhered to and doubt of the assignment to this species of Swedish materials is doubt, but the systematics of Eurasian hesperornithiforms are discussed.

A New Hesperornithid and the Relationships of the Mesozoic Birds
TLDR
One of the most important avian fossils is a nearly complete skeleton of a hesperornithid from the late Cretaceous Niobrara Chalk Formation of western Kansas found by H. T. Martin in 1894, that provides the basis for a re-evaluation of the relationships of the HesperORNithiformes to other Mesozoic birds.
MORPHOLOGY, PHYLOGENETIC TAXONOMY, AND SYSTEMATICS OF ICHTHYORNIS AND APATORNIS (AVIALAE: ORNITHURAE)
TLDR
This analysis provided a case study in the application of phylogenetic nomenclature at the species level and evaluated the relationships among Mesozoic ornithurines including Ichthyornis dispar and the newly identified taxa.
Description and ecologic analysis of Hollanda luceria, a Late Cretaceous bird from the Gobi Desert (Mongolia)
A redescription of Chaoyangia beishanensis (Aves) and a comprehensive phylogeny of Mesozoic birds
TLDR
Unique among ornithurines, Chaoyangia possesses two dorsal processes on the ischium, and thus remains a valid taxon and is included in a cladistic analysis to test morphological hypotheses regarding its systematic position.
THE MESOZOIC RADIATION OF BIRDS
TLDR
A wealth of recent discoveries combined with new phylogenetic analyses have documented the divergence of a number of lineages by the beginning of the Cretaceous, providing insights into the evolutionary development of feathers and other important features of the avian flight system.
Fossil that fills a critical gap in avian evolution
TLDR
The new taxon, Apsaravis ukhaana, is the best-preserved specimen of a Mesozoic ornithurine bird discovered in over a century and provides data important for assessing morphological evolution across Avialae, with implications for the monophyly of Enantiornithes and Sauriurae.
Neogaeornis wetzeli Lambrecht, a Cretaceous loon from Chile (Aves: Gaviidae)
TLDR
Neogaeornis has considerable temporal and biogeographic importance regardless of its identity, and after more than 60 years, a reappraisal of the type specimen is appropriate.

TLDR
Significant size and morphological differences and variation in flight capabilities, ranging from gliding to powerful flight among early birds, highlight the diversification of birds in the Early Cretaceous.
A new diverse enantiornithine family (Bohaiornithidae fam. nov.) from the Lower Cretaceous of China with information from two new species
TLDR
The robust morphology of the rostrum and foot suggests bohaiornithids occupied a specialized ecological niche compared to other Early Cretaceous enantiornithines.
