This includes the gray, purple, and red, mostly fluvial Stockton Formation as well as the 53 members that make up the lacustrine Lockatong mostly gray and black and Passaic mostly red formations. This list represents a very filtered version of information in the literature, and until more thorough studies can be completed it must be regarded as tentative and subjective. Each sequence of alluvial and lacustrine sediment accumulation is characterized by sediment derivation from a different source terrain. Aboul 2. It was originally thought by Lull to be a "pseudosuchian" allied to the Triassic aetosaur Stegomus, but later proved to be a Jurassic crocodile Walker, Sugarloaf Arkose sequences were deposited by braided rivers and streams.
Nonetheless, most of the variation is unequivocally real and is reflected not only in body shape, but also in scale and fin ray counts, and scale and skull bone morphology. Additional study is needed, however, because some coelacanths have an ossified lung which could be mistaken for a coprolite, and a source from other upper-level, aquatic predators such as sharks or protosuchian crocodiles cannot be completely ruled out. Of special interest is the Diplurus specimen collected and prepared by Alasdair Gilfillan, who has kindly allowed us to examine it. The next depositional break can be dated as being late Liassic, when open marine conditions were established.
Abstract The placement of the Carboniferous Pennsylvanian -Permian boundary in Kansas has been debated since the rocks of this age were first described and named. The striking resemblance between crocodile morphology and Batrachopus was first noted by Deane The Cowley Formation as originally defined and described by Lee in Kansas is reinstated. With this boundary the evolution at both North Atlantic margins becomes completely divergent.

Better preserved, more robust specimens are occasionally found in siltstone beds. They are the most common dinosaur footprint forms found in the Deerfield basin and in the Supergroup. This composite shows that the entire post-Stockton sedimentary section consists of a hierarchy of sedimentary cycles, thought to be of Milankovitch climate cycle origin.
Emmons first records the existence Stratigraphic nomenclature of the Newark Supergroup of eastern North America book fishes at Turners Falls, but detailed descriptions of the occurrence and systematics of the fossils have only recently been provided by McDonald and Olsen, et al.
They are not the full compliment of cycles present, but they are the most prominent ones and serve as reference and discussion points. With the mid-Cretaceous, correlations across the North Atlantic become difficult due to the installation of differing sedimentary and oceanographic regimes at both margins.
Follow access road up the mountain. What makes the first two localities interesting is the array of shapes and sizes of the abundant Semionotus that prompted the multitude of species names in the older literature. Therefore, the thickest part of the section is preserved along the axis of the syncline in the northern third of the basin.
Therefore we conclude that Otozoum is a prosauropod track. This slab, from the Portland Formation of the Hartford basin, was for many years a sidewalk stone in Middletown, Connecticut Lull, The thickness of any coastal plain strata that might have been deposited prior to Neogene sea level drop and erosion must have slight.
Aboul 2. In addition, organic matter preservation is higher, even in rooted, lake shore strata. The Late Cimmerian tectonics can be considered as the source of the next environmental change.
The names of biostratigraphic units consist of the name of the characteristic fossil plus the relevant unit term, e. At Callovian time, the first global sea level rise can be traced through all the basins. Also present are lower percentages of arauricarian conifer pollen, cycadophyte and ginkophyte pollen, fern and horsetail spores, pinacian conifer pollen, possible pteridosperm pollen, and a variety of enigmatic forms.
Thus, the evolution of the contiguous basins across the North Atlantic is found to be intimately linked during their Triassic, Jurassic and early Cretaceous history, but increasingly separated during late Cretaceous and Tertiary time. STOP 4.
In all cases the oldest name validly applied to each formation is given priority over more recently erected synonymous names, which are either abandoned or, in a few cases, changed in rank to a member of one of the formations recognized here.
Clasts are comprised of granite, schist, and quartzite, and are fairly well rounded. Information about this graben event is restricted to the northern and central transect.
Descend the hill between the parking area and the river to look at the outcrops upstream Locations Root traces represented by clay films, linear trains of rhizoconcretions, and rarely organic material are common in much of the section; however, there have been no systematic, paleoecologically-oriented studies of these root Stratigraphic nomenclature of the Newark Supergroup of eastern North America book in the Deerfield basin, or anywhere else in the Newark Supergroup for that matter.
Pollen and spores occur abundantly in fine gray siltstones and some claystones in the Fall River beds and Turners Falls Sandstone. Evidence of Jurassic terrestrial ecosystems in the basin consists of in situ trace fossils in the lake shore and playa strata, and allochthonous elements mostly wood, plant leaves, stems, pollen, and spores.
The name chosen for a stratigraphic unit should be unique to that unit. Especially frustrating are specimens in the cabinets; for these, there is no remaining order whatsoever. Regardless of the global trend towards higher efficiency, locally the lake shore and lake bed soils had low ecosystem efficiency.
The structure of the manus of Otozoum was the principle objection Baird, to assigning the genus to the prosauropod dinosaurs, as postulated by Lull Most of the Paleozoic structures parallel the later break-up of the Afro-American plate or the actual continental margins.
The term "Agawam Group," previously proposed to encompass all Newark Supergroup strata above the highest basalt of the Meriden Group, is here abandoned and replaced with the name "Portland Group" for the same suite of strata.Joint 52nd Northeastern Annual Section / 51st North-Central Annual Section Meeting - REVISING THE LOWER MISSISSIPPIAN STRATIGRAPHIC NOMENCLATURE IN THE PORTSMOUTH, OHIO REGION.

The Newark Rift Basin, formed during the breakup of Pangaea in the early Mesozoic, is one of the largest of exposed rift basins in eastern North America [Withjack et al., ; Olsen et al., ].
