Wooster’s Fossil of the Week: A fly in amber
A classic fossil this week. I wish I could say more about it. The specimen lost its label years ago, so I don’t know where it is from or its age (although a good guess is Neogene). I also can’t … Continue reading
Wooster’s Fossils of the Week: “Star-rock” crinoids from the Middle Jurassic of Utah
This little slab of crinoid stem fragments comes from the Co-op Creek Member of the Carmel Formation (Middle Jurassic) exposed in northwestern Kane County, Utah. I collected it with my friend Carol Tang as we explored a beautiful encrinite (a … Continue reading
Wooster’s Fossil of the Week: One sick crinoid from the Middle Jurassic of Israel
My first thought on seeing this distorted fossil was how much it evoked one of those Palaeolithic “Venus figurines“. It is certainly difficult to deduce that this is actually a crinoid column (or stem). It was found during my last … Continue reading
Wooster’s Fossil of the Week: A scolecodont from the Upper Ordovician of the Cincinnati region
This tiny but fearsome jaw is known as a scolecodont, and they are fairly common in the Cincinnatian rocks (Upper Ordovician) in the tri-state area of Ohio, Kentucky and Indiana. The label on this particular specimen does not indicate the … Continue reading
Wooster’s Fossil of the Week: A helpful echinoid from the Upper Cretaceous of Israel
These beaten-up fossils have served me well in the field this month. They are the regular echinoid Heterodiadema lybicum (Agassiz & Desor, 1846). They are common in the Cenomanian throughout northern Africa and the Middle East. These particular specimens, the … Continue reading

Wooster’s Fossils of the Week: A scleractinian coral and its tube-dwelling symbionts (Middle Jurassic of Israel)
I have a weakness for the beautiful scleractinian corals of the Matmor Formation (Middle Jurassic, Callovian-Oxfordian) of southern Israel. This particular specimen is Microsolena aff. M. sadeki from locality C/W-367 in Hamakhtesh Hagadol, southern Israel. (The “aff.” in the name … Continue reading
Wooster’s Fossil of the Week: An unusual scleractinian coral from the Upper Cretaceous of Israel
Originally this was going to be a mystery fossil for a crowd-sourced identification while I’m here in Israel doing fieldwork, but through the wonders of the internet I finally found a match for the strange fossil above: it is the … Continue reading

Wooster’s Fossil of the Week: A brontothere jaw fragment (Miocene of South Dakota)
This fossil has been sitting in a glass case outside my office door for nearly three decades. Only this year — in the desire to find more Fossils of the Week — did I bother to open the cabinet and … Continue reading
Wooster’s Fossil of the Week: Thoroughly encrusted brachiopod from the Upper Ordovician of Indiana
Last week was an intensely bored Upper Ordovician bryozoan, so it seems only fair to have a thoroughly encrusted Upper Ordovician brachiopod next. The above is, although you would hardly know it, the ventral valve exterior of a common strophomenid … Continue reading
Wooster’s Fossil of the Week: Intensely bored bryozoan from the Upper Ordovician of Kentucky
Yes, yes, I’ve heard ALL the jokes about being bored, and even intensely bored. I learn to deal with it. This week we continue to highlight fossils collected during our productive expedition to the Upper Ordovician (Cincinnatian) of Indiana (with … Continue reading
