Wooster’s Fossil of the Week: A crab’s meal from the Pliocene of Cyprus
This week’s fossil was collected on a Keck Geology Consortium expedition to Cyprus in the summer of 1996. My Independent Study student on that adventure was Steve Dornbos (’97), now a professor at the University of Wisconsin, Milwaukee (and a … Continue reading
Wooster’s Fossils of the Week: A foraminiferal ooze from the Pleistocene of Italy
On a recent field trip to Sicily, our paleontological party visited outcrops at Cala Sant’Antonino on the western side of the Milazzo Peninsula in the northwestern part of the island. We saw there an Early Pleistocene sedimentary unit informally called … Continue reading

Wooster’s Fossil of the Week: An almost planispiral gastropod from the Middle Jurassic of southern Israel
Add this to the list of fossils that have confused me. This summer, during a Wooster expedition, Lizzie Reinthal and Steph Bosch collected the above specimen from the Matmor Formation (Middle Jurassic, Callovian) of southern Israel. I simply assumed … Continue reading
Wooster’s Fossil of the Week: An irregular echinoid from the Middle Jurassic of southern Israel
From the view above, this fossil from the Matmor Formation (Middle Jurassic, Callovian) of southern Israel looks like your standard echinoid (a group that contains sea urchins and sand dollars), but turn it on its side (see below) and you … Continue reading
Wooster’s Fossil of the Week: An infected crinoid from the Middle Jurassic of southern Israel
This weathered beauty is a stem fragment of the articulate crinoid Apiocrinites negevensis from the Matmor Formation (Middle Jurassic, Callovian) of the Negev, southern Israel. The regular divisions you see making up the stem are the columnals, which look a … Continue reading
Wooster’s Fossils of the Week: Dinosaur teeth from the Cretaceous of Morocco
The fossil above is the best of a collection of dinosaur teeth given to us by the generous George Chambers (’79). The species that held it is the gargantuan theropod predator Spinosaurus aegyptiacus Stromer, 1915. The teeth are from Cenomanian … Continue reading

Wooster’s Fossils of the Week: Dinosaur footprints of unknown provenance
These are the only fossils in the Wooster collection I feel some shame about. They are tridactyl theropod dinosaur footprints. They are not spectacular, but they do the job for classes and visits by schoolchildren. I regret that we have … Continue reading
Wooster Geologists in Jerusalem
MITZPE RAMON, ISRAEL–This is the beautiful 400-year-old Turkish wall surrounding Jerusalem. It and virtually all the buildings in Jerusalem is made of “Jerusalem Stone” (a set of Cretaceous micritic limestones, to be pedantic). When the sun rises or sets on … Continue reading
Return to the Ora Formation
MITZPE RAMON, ISRAEL–The last location Wooster Geologists in Israel visited today was on the southern edge of the Makhtesh Ramon structure (N 30.58209°, E 34.89375°). Here are excellent exposures of the Ora Formation (Upper Cretaceous, Turonian). This curious feature was … Continue reading
Adventures in the Triassic: Exploring the Gevanim Valley in Makhtesh Ramon, southern Israel
MITZPE RAMON, ISRAEL–The second visit of the day for Wooster’s Team Israel 2013 was to the Gevanim Valley on the south side of the Makhtesh Ramon structure. This is a fascinating place where Cretaceous intrusions formed an uplifted dome exposing … Continue reading
