Abstract Phylogenetic divergence-time estimation has been revolutionized by two recent developments: 1) total-evidence dating (or "tip-dating") approaches that allow for the incorporation of fossils as tips in analysis, with their phylogenetic and temporal relationships to extant taxa inferred from data 2) fossilized birth-death (FBD) class tree models capture processes produce (speciation, extinction, fossilization) thus provide a coherent biologically interpretable prior. To explore...

Premise of research. A new Early Jurassic species Cupressaceae is reconstructed from the Cañadón Asfalto Formation in Argentina, based on impressions foliage and attached dispersed seed pollen cones.Methodology. Over 230 specimens were examined using reflected-light microscopy epifluorescence. Relevant extant taxa studied for structural comparisons herbarium living material botanical gardens. Relationships conifer assessed context currently known fossil used to evaluate morphological trends...
Compared to the osteological record of herbivorous dinosaurs from Late Cretaceous Prince Creek Formation northern Alaska, there are relatively fewer remains theropods. The theropod this unit is mostly comprised isolated teeth, and only non-dental known can be attributed troodontid cf. Troodon tyrannosaurid Nanuqsaurus. Thus far, presence members Dromaeosauridae has been limited teeth. Here we describe a symphyseal portion small dentary with two ziphodont Based on tooth shape, denticle...
Premise of the Study This article provides a workflow and protocol for paleobotanical researchers that integrates project-based fossil leaf specimen data collection with curation digitization. The methods aim to facilitate efficient digitization new collections by during course their study promote public databasing project data. Methods Results was developed refined reconstructing an extensive forest from impressions/compressions. consists field, museum, mobilization components. Customizing...
Sediments of the Woodbine Group exposed in northeastern Texas were deposited along southwestern margin Appalachia as a series near-shore, shoreline, distal lowland swamp, lake, and fluvial deposits during regression Western Interior Seaway early middle Cenomanian time. The Lewisville Formation (upper Group) north preserves most diverse terrestrial fossil assemblage known from Appalachia, but remains small ornithischian dinosaurs have been conspicuously absent it. An almost complete left...
Premise of research. Serotiny is a specialized dispersal mechanism in which seeds are retained on the parent plant and released following disturbance event. This strategy has evolved repeatedly plants inhabiting fire-prone regions typically requires adaptations for protection release seeds. We explore relationship between serotiny reproductive morphology Cupressaceae conifer clade, asking whether associated with evolution larger, more protective seed cones.Methodology. compiled cone volume...

During the last two decades, a wealth of data on biodiversity and associated environments has been mobilized in digital form. Collectively, these provide powerful resource that when curated integrated with intention, can critical information to address emerging complex global biological, environmental, public health challenges. Tapping into vast potential specimen, observation, environmental requires us integrate diverse multifaceted datasets, connect domain-specific communities, bridge...
Conifers of the taxodiaceous grade Cupressaceae were more diverse and widespread during Mesozoic than they are today. The earliest diverging subfamily, Cunninghamioideae, only includes a single extant genus, but has at least 10 fossil genera. Here, two additional cunninghamioid genera characterized on basis permineralized seed cones from Upper Cretaceous Hokkaido, Japan. These conifers display cone characters typical cunninghamioids; however, have mosaic that not seen in any reported conifer...
