Wooster’s Fossil of the Week: A Tully Monster! (Late Carboniferous of Illinois)
We have several examples of one of the strangest fossils known: Tullimonstrum gregarium Richardson 1966 — otherwise affectionately known as the Tully Monster. The above specimen is from the Francis Creek Shale Member (Carbondale Formation) at Mazon Creek near Chicago, … Continue reading
Wooster’s Fossil of the Week: a siliquariid gastropod (Eocene of Alabama)
It is hard to believe that this twisty tube is a snail, but it is. Tenagodus vitis (Conrad, 1835) is the scientific name for this worm-like gastropod from the Claiborne Sand (Eocene) of Alabama. It was originally named by Conrad … Continue reading
Wooster’s Fossil of the Week: A cornulitid (Late Ordovician of Indiana)
This may look like just another wormtube on a shell — a recurring theme on this blog — but it is special, of course. This is the common Paleozoic genus Cornulites Schlotheim 1820, specifically Cornulites flexuosus (Hall 1847). It was … Continue reading
Wooster’s Fossils of the Week: Eurypterids (Late Silurian of New York)
Few fossils are more dramatic than the long-extinct eurypterids. Above is one of Wooster’s best fossils: Eurypterus remipes De Kay 1825 from the Bertie Waterlime (Upper Silurian) of New York. (Thanks to Roy Plotnick for help with the identification.) As … Continue reading
Wooster’s Fossil of the Week: A new microconchid genus and species (Permian of Texas)
Two years ago I was invited to Texas by Tom Yancey (Texas A&M) to look at some curious wiggly tubular fossils in the Lower Permian (about 280 million years old). They form small reefs a meter or so across and … Continue reading
Wooster’s Fossil of the Week: an orthid brachiopod (Upper Ordovician of Indiana)
This beautiful brachiopod is Vinlandostrophia ponderosa (Foerste, 1909), an orthid brachiopod from the Maysvillian (Upper Ordovician) of southern Indiana. Until recently it had been traditionally known as Platystrophia ponderosa until a critical paper by Zuykov and Harper (2007) investigated the … Continue reading
Wooster’s Fossil of the Week: a baculitid ammonite (Cretaceous of Wyoming)
This is a specimen I often place on my Invertebrate Paleontology course lab tests. It is the “straight” ammonite Baculites, which is common enough, but the shell and internal walls (septa) have dissolved completely away, leaving this strangely articulated set … Continue reading
Wooster’s Fossil of the Week: an Italian keyhole limpet (Pliocene of Cyprus)
This week’s fossil is a beautiful little gastropod (snail) scientifically known as Diodora italica (Defrance, 1820), and commonly as the Italian Keyhole Limpet. I collected it with Steve Dornbos (’97) during the 1996 Keck Geology Expedition to Cyprus, where it … Continue reading
Exploring the Silica Formation (Middle Devonian) in Northwestern Ohio
PAULDING, OHIO–There’s nothing like the stirring rings of 50 geologic hammers in the morning. Today I was a guest of the North Coast Fossil Club and my friend Brian Bade in a quarry exposing the Middle Devonian limestones and shales. … Continue reading
How Fossils Saved Civilization: A National Fossil Day Talk
WOOSTER, OHIO — National Fossil Day has now been in place for two years. Curiously enough, two Wooster alumnae, Erica Clites and Eva Lyon, have been critical organizers and promoters of this great event as Paleontology Interns with the National … Continue reading
