  • Ecomorphological associations of scapulocoracoid form in Greater Antillean Anolis lizards. [Journal Article]
    Ann Anat. 2020 May 04; 231:151527.Tinius A, Russell AP, … Anderson JS
  • External morphological metrics have featured prominently in comparative studies examining the morphological convergence that characterizes anoline ecomorphs. To what degree the appendicular-skeletal morphology of Greater Antillean island Anolis lizards tracks their diversity and ecological adaptation, however, remains relatively unexplored. Here we employ computed tomographic scanning techniques …
  • Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus. [Journal Article]
    PeerJ. 2020; 8:e8493.Evers SW, Foth C, Rauhut OWM
  • Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various aspects of…
  • Two new species in the genus Andronymus Holland, 1896 (Lepidoptera, Hesperiidae). [Journal Article]
    Zootaxa. 2019 Jun 27; 4624(1):zootaxa.4624.1.7.Sáfián S, Belcastro C, Tropek R
  • During extensive field work in West Africa (Cameroon, Ivory Coast, Liberia, Sierra Leone), the authors collected two skipper species in the genus Andronymus (Lepidoptera, Hesperiidae), which would not fit the descriptions of any existing taxa. Both are described as new, A. magma sp. nov. is known only from Cameroon, while A. fenestra sp. nov. was found in a few localities in the Liberian sub-regi…
  • The development of the osteocranium in the snake Psammophis sibilans (Serpentes: Lamprophiidae). [Journal Article]
    J Anat. 2020 Jan; 236(1):117-131.Al Mohammadi AGA, Khannoon ER, Evans SE
  • Non-avian reptiles are good models to investigate structural and developmental differences between amniotes. Investigations of craniofacial development in a complete series of embryos from oviposition up to hatching are still relatively rare. Consideration of a complete series can reveal developmental events that were previously missed, and thus correct or confirm theories about developmental eve…
  • New Material of Sinopterus (Pterosauria, Tapejaridae) from the Early Cretaceous Jehol Biota of China. [Journal Article]
    An Acad Bras Cienc. 2019 Jun 27; 91(suppl 2):e20180756.Zhang X, Jiang S, … Wang X
  • Tapejaridae is a clade of toothless pterosaurs typically characterized by a large nasoantorbital fenestra and a premaxillary crest that extends from the anterior to the posterior part of the skull. Sinopterus dongi was the first reported Chinese tapejarid. Another genus "Huaxiapterus" was described, but it was later on determined that "Huaxiapterus" is in fact an invalid name. Here, we report o…
  • Dolichocebus gaimanensis Is Not a Stem Platyrrhine. [Journal Article]
    Folia Primatol (Basel). 2019; 90(6):494-506.Rosenberger AL
  • The lower molars of the early Miocene New World monkey Dolichocebus gaimanensis from Patagonia, considered by some to be a stem platyrrhine, are for all intents and purposes indistinguishable from the same teeth preserved in the type specimen of the middle Miocene Laventiana annectens from Colombia. Canine morphology further indicates that Dolichocebus is a cebine, closely related to living Saimi…
  • First Report of the Yellow Nutsedge Cyst Nematode, Heterodera cyperi, in Georgia, U.S.A. [Journal Article]
    J Nematol. 2018; 50(3):456-458.Hajihassani A, Dutta B, … Subbotin SA
  • Soil samples collected during a survey for plant-parasitic nematodes in Tift County GA in summer 2017 were submitted for routine diagnosis of nematodes to the Extension Nematology Lab at the Department of Plant Pathology, University of Georgia, Athens, Georgia. Cyst nematodes recovered by centrifugal flotation technique were discovered in the samples from two research sites in a field with a hist…
