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

Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C

The expensive-tissue hypothesis may help explain brain-size reduction during domestication
Morphological traits, such as white patches, floppy ears and curly tails, are ubiquitous in domestic animals and are referred to as the ‘domestication syndrome’. A commonly discussed hypothesis that has the potential to provide a unifying explanation for these traits is the ‘neural crest/domestication syndrome hypothesis’. Although this hypothesis has...Lesch, Raffaela ; Kotrschal, Kurt ; Kitchener, Andrew C ; Fitch, W Tecumseh ; Kotrschal, Alexander

Evidence that Temminck described Felis aurata in 1825, not 1827
The African golden cat, Caracal aurata, ranges from west through central to east Africa and is categorized as Vulnerable on the IUCN Red List of Threatened Species. Coenraad J. Temminck (1778–1858) described Felis aurata (African golden cat) and other new felid species in the fourth of seven monographs collected in... -

Novel mtDNA haplotypes represented in the European captive population of the Endangered François’ langur (Trachypithecus francoisi)
Assessing the genetic diversity of captive populations of endangered species is key to the successful management of conservation-breeding programs. In this study, we sequenced a 393-bp fragment of the mitochondrial DNA (mtDNA) control region of 23 captive individuals of the Endangered François’ langur ( ) to assess the mtDNA diversity...Farré, Marta ; Johnstone, Cameron ; Hopper, Jane ; Kitchener, Andrew C ; Roos, Christian …

First British record of the short-finned pilot whale
What is the difference between the long-finned and the short-finned pilot whale? Andrew Kitchener explains how the examination of the skull of a stranded whale revealed the true identity of the species and the most northerly stranding of a short-finned pilot whale in the northeast Atlantic.Kitchener, Andrew C

Psittacopedids and zygodactylids: The diverse and species-rich psittacopasserine birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK)
The Daniels collection of fossil birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK) contains multiple specimens of the Psittacopedidae and Zygodactylidae, which are here for the first time studied in detail. The Psittacopedidae include Parapsittacopes bergdahli, Psittacomimus eos, gen. et sp. nov., ?Psittacopes occidentalis, sp. nov., and...Mayr, Gerald ; Kitchener, Andrew C

Machine learning ATR-FTIR spectroscopy data for the screening of collagen for ZooMS analysis and mtDNA in archaeological bone
Faunal remains from archaeological sites allow for the identification of animal species that enables the better understanding of the relationships between humans and animals, not only from their morphological information, but also from the ancient biomolecules (lipids, proteins, and DNA) preserved in these remains for thousands and even millions of... -

A kingdom in decline: Holocene range contraction of the lion (Panthera leo) modelled with global environmental stratification
Aim We use ecological niche models and environmental stratification of palaeoclimate to reconstruct the changing range of the lion (Panthera leo) during the late Pleistocene and Holocene. Location The modern (early 21st century) range of the lion extends from southern Africa to the western Indian Subcontinent, yet through the... -

The Scientific Name of the Aardwolf is Proteles cristatus
The aardwolf is one of the four members of the family Hyaenidae (order Carnivora). It is referred to as either Proteles cristatus or Proteles cristata in the scientific literature and on animal diversity websites, but only one of these names is correct. In this short note, we seek to rectify...Werdelin, Lars ; Kitchener, Andrew C ; Abramov, Alexei ; Veron, Géraldine ; Do Linh San, Emmanuel
