The conodont animal
A unique specimen of a small, elongate, soft-bodied animal from the Lower Carboniferous of the Edinburgh district, Scotland, is described. The head expands anteriorly into two lobate structuresExpand
The anatomy of conodonts
Ten specimens from the Carboniferous Granton shrimp bed of Edinburgh, Scotland, provide the most complete record of conodont anatomy, with evidence of incomplete preservation of ventral soft parts, at least at the anterior end of the specimens. Expand
The Lower Carboniferous shrimp Tealliocaris from Gullane, East Lothian, Scotland
Tealliocaris is probably one of the best preserved of all Carboniferous crustaceans. It occurs scattered through the 12 cm thick laminated Gullane ‘shrimp-bed’. The cuticle is exceptionally wellExpand
The Post-Ecdysial Development of the Cuticle and the Eye of the Devonian Trilobite Phacops rana milleri Stewart 1927
The post-ecdysial development of the cuticle and the schizochroal compound eye has been studied in a suite of specimens representing various stages, culminating in the intermoult condition and some suggestions are made regarding function in the developing eye. Expand
Trilobite eyes and the optics of Des Cartes and Huygens
The thick lenses in the aggregate eyes of a group of trilobites were doublet structures designed to eliminate spherical aberration and may have evolved such sophisticated eye-lenses to maximise optic neurone response in a dimly lit environment. Expand
Late Ordovician Foreland Basin Fill: Long Point Group of Onshore Western Newfoundland
ABSTRACT The Long Point Group (Caradoc) is the only representative of Late Ordovician foreland basin deposits exposed onshore in the southwestern Newfoundland segment of the Appalachian Orogen. ThisExpand
Shrimp-bearing sedimentary successions in the Lower Carboniferous (Dinantian) Cementstone and Oil Shale Groups of northern Britain
The Lower Carboniferous of northern Britain is dominated by non-marine sequences which yield fish and crustacean faunas. These are rarely preserved and occur in thin layers. The sedimentology ofExpand
Evolution of the Northern Belt, Southern Uplands: implications for the Southern Uplands controversy
Conodont and graptolite dating provide a high resolution biostratigraphical framework for correlation across the Southern Upland Fault. The establishment of an early Caradoc age for the red chert andExpand
Structure, ontogeny, and moulting of the olenid trilobite Ctenopyge (Eoctenopyge) angusta Westergård, 1922 from the upper Cambrian of Västergötland, Sweden
The abundant Ctenopyge (Eoctenopyge) angusta Westergard, 1922 is described and reconstructed here as an adult, and the entire ontogeny is documented for all post–protaspid growth stages. Expand
Faunal turnovers and trilobite morphologies in the upper Cambrian Leptoplastus Zone at Andrarum, southern Sweden
The Furongian (upper Cambrian) Leptoplastus Zone marks a time of critical changes in the evolution of olenid trilobites. This zone, unexposed at Andrarum in Skane, southern Sweden, has beenExpand
