Exploring the top of the Matmor Formation (Middle Jurassic) in Makhtesh Gadol

MITZPE RAMON, ISRAEL — Today I joined four Israeli colleagues to study in detail the top of the Matmor Formation (Callovian, Middle Jurassic) in Makhtesh Gadol, Negev Highlands, southern Israel. The view above is looking south in the Matmor Hills along this upper section. You can see why this kind of exposure is popular with […]

A day in the Zohar and Matmor Formations of the Negev

MITZPE RAMON, ISRAEL — It was another very windy day in southern Israel, but still just fine for fieldwork. Yael Edelman-Furstenburg, Yael Leshno and I returned to Makhtesh Gadol to work on Yael Leshno’s data collection procedures for her PhD project in the Middle Jurassic sequence here. Our first task was figuring out the detailed […]

Last work of Team Israel, Matmor Division

WOOSTER, OHIO–Steph Bosch (’14) and Lizzie Reinthal (’14) volunteered to examine the Matmor Formation fossils I collected last month in Israel. Each fossil, most of which are crinoid ossicles, must be scanned under a microscope for tiny encrusters (especially bryozoans), borings, and bite marks. In the image above you can see the collection bags on […]

Patchiness and ecological structure in a Middle Jurassic equatorial crinoid-brachiopod community (Matmor Formation, Callovian, southern Israel) — An abstract submitted to the Geological Society of America for the 2012 annual meeting

Editor’s note: The Wooster Geologists in Israel this spring wrote abstracts for the Geological Society of America Annual Meeting in Charlotte, North Carolina, this November. The following is from student guest blogger Melissa Torma in the format required for GSA abstracts: TORMA, Melissa, WILSON, Mark A., Department of Geology, The College of Wooster, Wooster, OH […]

Wooster’s Fossils of the Week: A calcareous sponge with a crinoid holdfast (Matmor Formation, Middle Jurassic, Israel)

The Class Calcarea of the Phylum Porifera is a group of sponges characterized by spicular skeletons made of calcium carbonate (calcite in this case). The spicules (small elements of the skeleton) are often fused together, causing the sponges to look a bit like corals or bryozoans. They are among the most common fossils in the […]

Wooster’s Fossil of the Week: A mytilid bivalve from the Middle Jurassic of southern Israel

This week’s specimen comes from one of my favorite fossiliferous units: the Matmor Formation (Middle Jurassic, Callovian) of Makhtesh Gadol in southern Israel. I’ve been delighted by the fossils and lithologies of the Matmor since 2003. This particular fossil is exposed in a bedding plane of the very rich subunit 65, which I’ve mentioned before […]

A Wooster Geologist visits the caves of Tel Maresha in central Israel

TEL AVIV, ISRAEL — My last day in Israel was spent with my friend Yoav Avni exploring some sites in the central part of the country before my flight left Tel Aviv late in the evening. The most geological place we visited was Maresha (which later became, in order, Beit Guvrin, Eleutheropolis, Bethgibelin, Bayt Jibrin, […]

Last day of fieldwork in Israel: More Jurassic enjoyment

MITZPE RAMON, ISRAEL — For my last day of fieldwork during this short Spring Break trip to Israel, I returned to Makhtesh Gadol to collect a bit more data from subunits 65 and 66 of the Matmor Formation (Middle Jurassic, Callovian). The above image shows part of my field site in the Meredith section north […]

At some point you must start collecting data

MITZPE RAMON, ISRAEL — Today my friend Yoav Avni (Geological Survey of Israel) and I returned to Makhtesh Gadol to pursue a project with Subunit 65 of the Matmor Formation (Callovian, Middle Jurassic). You may recall this limestone contains an extraordinary bedding plane of fossils preserved in near-life positions (as seen in a recent Fossil […]

Wooster’s Fossils of the Week: A Jurassic seafloor assemblage

Images from fieldwork this week. These are all fossils exposed on a single bedding plane in the Matmor Formation (Middle Jurassic, Callovian) exposed in Makhtesh Gadol. I found them many years ago while working through the stratigraphy near the top of the formation. They present a vignette of life in a shallow carbonate Jurassic sea. […]
