On the “screamer-like” birds from the British London Clay: An archaic anseriform-galliform mosaic and a non-galloanserine “barb-necked” species of Perplexicervix
We revisit recently described putative anseriform birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). Phylogenetically relevant skeletal elements of Danielsavis nazensis Houde et al., 2023 are reported that were omitted from the original description, including the pterygoids and palatines. We detail that anseriform affinities of D. nazensis...Mayr, Gerald ; Carrió, Vicen ; Kitchener, Andrew C

Oldest fossil loon documents a pronounced ecomorphological shift in the evolution of gaviiform birds
We describe a stem group representative of Gaviiformes (loons or divers) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Nasidytes ypresianus gen. et sp. nov. is a partial skeleton including the mandible and all major limb bones. The new species is the oldest unambiguously identified...Mayr, Gerald ; Kitchener, Andrew C

Best practices for digitally constructing endocranial casts: examples from birds and their dinosaurian relatives
The rapidly expanding interest in, and availability of, digital tomography data to visualize casts of the vertebrate endocranial cavity housing the brain (endocasts) presents new opportunities and challenges to the field of comparative neuroanatomy. The opportunities are many, ranging from the relatively rapid acquisition of data to the unprecedented ability...Balanoff, Amy M ; Bever, G S ; Colbert, Matthew W ; Clarke, Julia A ; Field, Daniel J …
