Journal ArticleDOI
The oldest articulated chondrichthyan from the Early Devonian period
TL;DR: This specimen is the oldest shark showing the tooth families in situ, and preserves one of the oldest chondrichthyan braincases, and shows the presence of paired pectoral fin-spines, previously unknown in cartilaginous fishes.
Journal ArticleDOI
Resolving MISS conceptions and misconceptions: A geological approach to sedimentary surface textures generated by microbial and abiotic processes
TL;DR: In this article, the authors introduce the umbrella term "sedimentary surface textures" and propose a methodology for classifying such structures in the geological record, and demonstrate that morphological similarity alone does not constitute scientific proof of a common origin, and reinstates a passive descriptive terminology for sedimentary surface textures that cannot be achieved with the current MISS lexicon.
Journal ArticleDOI
Paleoecology of Early Pennsylvanian vegetation on a seasonally dry tropical landscape (Tynemouth Creek Formation, New Brunswick, Canada)
Arden R. Bashforth,Arden R. Bashforth,Arden R. Bashforth,Christopher J. Cleal,Martin R. Gibling,Howard J. Falcon-Lang,Randall F. Miller +6 more
TL;DR: The distribution and community ecology of Early Pennsylvanian vegetation on a seasonally dry fluvial megafan is reconstructed from plant assemblages in the Tynemouth Creek Formation of New Brunswick, Canada.
Journal ArticleDOI
The braincase of the chondrichthyan Doliodus from the Lower Devonian Campbellton Formation of New Brunswick, Canada
TL;DR: Doliodus has curious bar-like, paired subcranial ridges ending posteriorly at the hyomandibular articulation, adding circumstantial palaeontological support to the old proposal that parts of visceral arches may be incorporated into the gnathostome braincase, although it seems more plausible that they formed in the lateral margins of the embryonic parachordal or hypotic lamina.
Journal ArticleDOI
Climatic implications of D/H ratios in beetle chitin
TL;DR: Hydrogen isotopic analyses of beetle chitin demonstrate the potential for development of a palaeoclimatic tool that can be used to complement current palaeoentomological methods, and demonstrate small interspecific and intraspecific variation in beetles of different habit.
