The first records of the pictured-winged fly Homalocephala bimaculata (Wahlberg, 1838) (Diptera, Ulidiidae) from Norway
The picture-winged fly Homalocephala bimaculata (Wahlberg, 1838) is reported from Norway for the first time bringing to five the number of species of Homalocephala Zetterstedt, 1838 reported from the country. H. bimaculata is recorded from Hvaler, Viken, and Oslo, Oslo, and, based on numerous and scattered records, the species is...Gustad, Jørn R ; Græsdal, Arve G ; MacGowan, Iain

Re-description of two contemporaneous mesorostrine teleosauroids (Crocodylomorpha: Thalattosuchia) from the Bathonian of England and insights into the early evolution of Machimosaurini
Teleosauroidea was a clade of successful, morphologically diverse, ancient crocodylomorphs that were integral in coastal marine/lagoonal environments during the Jurassic. Within Teleosauroidea, the macrophagous/durophagous tribe Machimosaurini evolved specialized feeding strategies (e.g. hypertrophied jaw musculature and blunt, heavily ornamented dentition) and large body sizes (> 7 m), becoming an important component... -

Emptying the wastebasket: a historical and taxonomic revision of the Jurassic crocodylomorph Steneosaurus
Teleosauroidea is a clade of ancient crocodylomorphs that were integral components of coastal marine environments throughout the Jurassic. For nearly two centuries, one of the most familiar genera of teleosauroids has been Steneosaurus, encompassing nearly every teleosauroid species at some point. However, no type species has been designated for Steneosaurus... -

Macroevolutionary trends in the genus Torvoneustes (Crocodylomorpha: Metriorhynchidae) and discovery of a giant specimen from the Late Jurassic of Kimmeridge, UK
The metriorhynchid crocodylomorph fauna of the Late Jurassic Kimmeridge Clay Formation (KCF) of the UK was highly diverse. One genus from this Formation, Torvoneustes, was unique in evolving dentition similar to known chelonivorous crocodylomorphs and enlarged attachment sites for the pterygoideus adductor musculature. Here we report the largest known Torvoneustes...macroevolution, body-size, Metriorhynchoidea, Kimmeridgian, Geosaurinae, and Torvoneustes

The phylogenetics of Teleosauroidea (Crocodylomorpha, Thalattosuchia) and implications for their ecology and evolution
Teleosauroidea was a clade of ancient crocodylomorphs that were a key element of coastal marine environments during the Jurassic. Despite a 300-year research history and a recent renaissance in the study of their morphology and taxonomy, macroevolutionary studies of teleosauroids are currently limited by our poor understanding of their phylogenetic... -

Scientists, collectors and illustrators: the roles of women in the Palaeontographical Society
Women have taken on a range of roles in scientific societies since the early twentieth century. The oldest society dedicated to palaeontology, the Palaeontographical Society, was established in 1847 principally for the publication of monographs on British fossils. Since its foundation, women have been involved, initially as collectors and illustrators,... -

Identification of the Afrotropical lance fly Silba laevis (Bezzi, 1920) (Diptera: Lonchaeidae) imported into the United Kingdom
The lonchaeid or lance fly Silba laevis (Bezzi, 1920) is recorded for the first time on aubergine (Solanum melongena L.) having been successfully reared from aubergines imported into the United Kingdom (U.K.). The following manuscript provides detailed photographs and drawings of S. laevis, reviews recent interception data and briefly comments...Solanum, Lonchaeidae, aubergine, plant-health, Silba, and Kenya

Enigmatic vertebrate trackway from the Scalby Formation (Middle Jurassic) Yorkshire, United Kingdom, with discussion of archosaur and ‘mammal’ trace fossils
We describe a new and unusual vertebrate trackway from the Middle Jurassic Scalby Formation of the Cleveland Basin, Yorkshire, United Kingdom. The Enigmatic Burniston Trackway (EBT) is the first and only example of such a trackway known from this region. The best preserved EBT print, belonging to a pentadactyl tetrapod,...synapsid, Sederipes, Synaptichnium, Ravenscar Group, and Footprint
