The use of a “map portal” allows researchers to publish their maps and the data incorporated therein in a simple way that will reach a broad audience. Colleagues, as well as other workers worldwide, can connect to the portal through the internet and display the maps on desktop computers. The process is dynamic; any change made in the source map is immediately displayed on the user’s desktop. In this report we illustrate a map of Triassic and Jurassic brachiopod collecting localities on the southern Tethyan margin in the Middle East. The locations are shown as red points that overlie a …
The Triassic Saharonim Formation Of The Sephardic Province On The Southern Tethyan Margin Is An Analog For The Triassic Germanic Muschelkalk Of Western Europe, Howard R. Feldman, Talia J. Belowich
The Triassic Saharonim Formation Of The Sephardic Province On The Southern Tethyan Margin Is An Analog For The Triassic Germanic Muschelkalk Of Western Europe, Howard R. Feldman, Talia J. Belowich

The Germanic Muschelkalk consists of a sedimentary sequence of limestone and dolostone units that overlies the Permian Buntsandstein Formation and underlies the Middle and Late Triassic Keuper Formation. The three formations form the Germanic Triassic Supergroup. The Muschelkalk was deposited in a shallow marine environment that was only partially connected to the Tethys Ocean to the south with the middle section evaporitic indicating a restricted basin. Fossiliferous beds are often biostromal such as the well-known Coenothyris brachiopod beds (e.g. Terebratula Bed, terebratulid facies) common in the Muschelkalk. The Saharonim Formation of the Sephardic Province, found along the southern shore of …
A Unique Petroglyph Carving On The Shawangunk Ridge, Lower Hudson Valley, New York, Howard R. Feldman
A Unique Petroglyph Carving On The Shawangunk Ridge, Lower Hudson Valley, New York, Howard R. Feldman
Lander College for Women - The Anna Ruth and Mark Hasten School Publications and Research
A unique circular petroglyph from the Shawangunk Ridge in the lower Hudson Valley, New York was found carved into the resistant metaconglomerate/quartzitic rock not far from Mohonk Mountain House. The Shawangunk Formation crops out near Rosendale, New York and extends in a general southwestward direction accessible along Route 17 near Wurtsboro, again at the Delaware Water Gap and then can be traced in into Pennsylvania and Virginia. The ridge and surrounding area (e.g. Wallkill Valley) is lacking in chert, a vital raw material used in the carving of petroglyphs (Feldman, et al., 2016). However, there are numerous other examples of …
Dielasma Or Tunethyris? A Taxonomic Conundrum, Howard R. Feldman, Talia J. Belowich, Tova Braver, Sarah Laks
Dielasma Or Tunethyris? A Taxonomic Conundrum, Howard R. Feldman, Talia J. Belowich, Tova Braver, Sarah Laks
Lander College for Women - The Anna Ruth and Mark Hasten School Publications and Research
A new species of a dielasmid brachiopod from the Triassic Saharonim Formation of Makhtesh Ramon, southern Israel, was discovered in Anisian-Ladinian limestones that alternate with calcareous shales. The environment of deposition was an open shelf with normal salinity. The new species is homeomorphic with Paleozoic forms, but may not belong to the genus Dielasma; however, it may be a species of Tunethyris, a Triassic genus from Tunisia. If the Triassic specimens belong to the Paleozoic genus Dielasma, an important new Lazarus genus is added to the systematic literature. However, if the specimens belong to the Triassic Tunethyris, …

The Middle Silurian Shawangunk Formation crops out in the lower Hudson Valley and extends toward the southwest into New Jersey and Pennsylvania. It reaches a maximum thickness around Guymard (1,400 ft.; 400m) and gradually thins toward the northeast, pinching out near Binnewater, New York. The formation consists of gray conglomerate, quartz arenite, and minor shale. Worm burrows, Arthrophycus, Skolithos, Planolites?, and a bilobed resting trace have been found at different stratigraphic horizons in the Shawangunk Formation. All traces are associated with a finer, sandy matrix and/or hematite-rich interval rather than a coarse, pebbly quartz sandstone lithology dominant in the bulk …
A Dielasma Community From The Triassic Of Makhtesh Ramon, Southern Israel, Howard R. Feldman, Alexa J. Belowich
A Dielasma Community From The Triassic Of Makhtesh Ramon, Southern Israel, Howard R. Feldman, Alexa J. Belowich
Lander College for Women - The Anna Ruth and Mark Hasten School Publications and Research
The cosmopolitan brachiopod Dielasma ranges from the Upper Mississippian through the Upper Triassic. In southern Israel a new Dielasma community is recognized from the Triassic Saharonim Formation, Ramon Crater. The shells represent a new species and are very strongly sulciplicated, a feature that seems to be more prevalent in the Mesozoic than the Paleozoic. The Saharonim Formation was deposited under normal, calm, relatively shallow marine conditions as part of the global transgression of the Early Ladinian sea. There is no evidence of evaporitic or dolomitic sediments. The complete absence of scouring within the carbonates or signs of channeling and ripple …
An Unusual Occurrence Of Arthrophycus Alleghaniensis(?) On The Shawangunk Ridge, Lower Mid-Hudson Valley, New York, Howard R. Feldman, Alexander Bartholomew, Beryl Kahn

The Shawangunk Formation is a medial Silurian conglomerate that crops out from near Rosendale, south through Wurtsboro, New York, High Point State Park and the Delaware Water Gap in New Jersey, and at Lehigh Gap, Pennsylvania after which it continues into Maryland and Virginia. The formation overall is interpreted to primarily represent a braided stream environment with flowage from mountains to the east that arose during the Taconic Orogeny into a basin toward the west. The trace fossil Arthrophycus was found in the upper-middle part of the formation on the Shawangunk Ridge at Mohonk, near New Paltz, New York. Arthrophycus …

Lander College for Women - The Anna Ruth and Mark Hasten School Publications and Research
A Jurassic (Bathonian-Callovian) brachiopod fauna from Jordan consists of seven rhynchonellid species all belonging to the genus Daghanirhynchia of which two are new: Daghanirhynchia rawyaensis and D. jordanica. Emended diagnoses are given for Daghanirhynchia daghaniensis and D. macfadyeni. Additional taxa described include Daghanirhynchia angulocostata, D. susanae and D. triangulata. Threedimensional reconstructions illustrate the internal morphology of the articulated shells for the first time in this genus. The material studied herein was collected from Wadi Zarqa in northwestern Jordan, almost due north of the Dead Sea, and to the east of the Rift Valley. Most species seem to be geographically restricted …
