Late Devonian glaciation in South America
Palaeogeography, Palaeoclimatology, Palaeoecology, 1985Abstract An ice age in Famennian (Late Devonian) time is documented by the presence of diamictites with striated, faceted and polished pebbles; rhythmites with dropstones; erratic boulders; and striated pavements and deformed sandstones. The glacigenic beds occur in three huge intracratonic basins (Solimoes, Amazonas and Parnaiba) and in one ...

Pseudoextinctions in late Devonian proetide trilobites
Historical Biology, 1994Morphologically similar proetide trilobite genera occur in highest Devonian or lowest Carboniferous and in Middle Devonian strata, but are absent from the intervening Upper Devonian. The similarities have been accounted for either by true phyletic relationship, or by homoeomorphy.

Late Devonian sphenopsid shows evidence of aquatic adaptations
Current BiologyVascular plants diversified and adapted to various terrestrial environments during the Silurian and Devonian periods and had formed complex forests by the Middle and Late Devonian1. However, fossil evidence of functional adaptations to aquatic environments remains scarce, from forms with only submerged subterranean parts to fully submerged types ...

Insight into lingulid evolution from the Late Devonian
Alcheringa: An Australasian Journal of Palaeontology, 1977Well preserved lingulids from near the base of the Mandagery Sandstone in the Late Devonian Hervey Group, N.S.W. are described as Apsilingula parkesensis gen. et sp. nov. The internal structures are better preserved than those of any previously described Palaeozoic lingulid and it has been possible to reconstruct the muscle system and to demonstrate a ...

Late Devonian vertebrate fauna of the South Urals
Geobios, 1995Abstract Vertebrate remains have been discovered in the Frasnian and Famennian of the South Urals The ichthyofaunacontains representatives of Phoebodus; Stethacanthus; Symmorium; Protacrodus as well as placoderms; acanthodians; “crossopterygians” dipnoans and palaoniscids. Changes of the fish assemblages are examined. A review of the occurrences of

Late Devonian syntaxis in the Northern Appalachian orogen
Geological Society, London, Special PublicationsAbstract The pre-accretionary shapes of cratonic margins form successions of promontories and re-entrants inherited from the rifting of supercontinents. In accretionary orogens, the extent of deformation related to a collision with a continent characterized by an irregular margin is obfuscated through the ...

Visceral skeleton and musculature of a Late Devonian shark
Journal of Vertebrate Paleontology, 1989ABSTRACT Much of the visceral skeleton (jaws, hyoid arch, and branchial arches) and superficial orobranchial musculature is described from an unique three-dimensionally preserved cladoselachian from the Upper Devonian Chattanooga Shale of Tennessee. The mandibular joint lacks the complexity seen in modern chondrichthyans.

A review of in situ late Silurian and Devonian spores
Review of Palaeobotany and Palynology, 1980Abstract Spores found in sporangia have now been recorded in the literature from sixty Late Silurian and Devonian macroplant species. A review study of these spores, together with an investigation of comparative dispersed spore genera and species, show interesting patterns of construction and sculpture within certain classes.
