The Ellimmichthyiformes is an extinct order of clupeomorph fishes. This group includes fossil species from marine, estuarine, and freshwater sediments ranging in time from the Early Cretaceous to the Eocene. In spite of the long history of taxonomic studies on the Clupeomorpha, phylogenetic...
Extinct snake taxa are primarily recognized from isolated vertebrae. A new specimen from the Oligocene of Wyoming provides a rare opportunity to examine four nearly complete and articulated fossil snakes. Informally assigned previously to the ‘erycine’ vertebral form taxa Ogmophis and...
Living platynotan lizards are represented by two families: Helodermatidae, consisting of two species limited to south-western North America and north-western Central America; and Varanidae, with 54 species distributed throughout Africa, south-east Asia and Australia. Modern members of Platynota,...
Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...
Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid FishesDownload
Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when...
With well over 3,400 described species, snakes undoubtedly represent one of the most successful groups of reptiles. Much has been written about their ecology, behavior, anatomy, relationships and evolution. However, despite the debate about the origin of this taxonomic group dating back to the...
Pachyrhinosaurus is a peculiar ceratopsian known only from Upper Cretaceous strata of Alberta and the North Slope of Alaska. The genus consists of three described species Pachyrhinosaurus canadensis, Pachyrhinosaurus lakustai, and Pachyrhinosaurus perotorum that are distinguishable by cranial...
Lactobacillus reuteri is a common organism in cereal-based foods and a gut symbiont in humans and animals, yet the molecular mechanisms allowing its persistence in various niches are not well understood. L. reuteri LTH2584 produces reutericyclin and persists in industrial sourdoughs, where acidic...
