11:00 "Valley of the T-Rex" by Discovery Channel (DVD)

This DVD from the Discovery Channel explores the discovery and removal of T-Rex skeletons from Montana’s Hell Creek Formation and how the bones got
there in the first place.



"Mississippian Crinoids" by Tom Williams (Speaker)

Tom is a geology graduate of Western Illinois University in Geology and received a Master of Science
in Geohydrology at Illinois State. He has worked for 30 plus years as a geologist. He has specialised in
collecting Crinoids in the Mississippian Chesterian age since 1980, contributing knowledge and some
important specimens while collecting with other researchers. In 1998 he worked with Dennis Burdick
on a major crinoid dig found in situ in the Chesterian of Alabama which uncovered many important
specimens including whole plates up to five feet by five feet with some specimens having stems five to six
feet long. Another trip to Lance formation in Wyoming yielded a Cretaceous fossil flowering plant that
may be used for research.



"Bigger Than T-Rex" by NOVA (DVD)

Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus rex, perhaps the largest predator ever
to roam the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus.
Now, the discovery of new bones in a Moroccan cliff face is reopening the investigation into this epic beast. We follow the paleontologists who are
reconstructing this terrifying carnivore, revealing a 53-foot-long behemoth with a huge dorsal sail, enormous, scimitar-like claws, and massive jaws tapered toward
the front like a crocodile.


4:30 "Danville's Fossil Forest " by Scott Elrick, ISGS (DVD)
Scott Elrick will describe a 300-million-year-old fossilized forest, found near Danville, Illinois.
At just under 10 square miles, the forest’s sheer size offers an unprecedented view of ancient forest life
and diversity. This rare find, discovered in the roof of an underground coal mine, opens a tantalizing
window into the past. The forest plants and their encapsulating geology reveal much about the ancient
environmental conditions during the time of their formation and about the coal they left behind.

12:00 "The End-Permian Extinction" By Dr. Thomas Hegna (Speaker)

Dr. Hegna teaches History of the Earth, Paleontology, mineralogy and Integrated Science at WIU.
At the end of the Paleozoic, the Earth saw its largest extinction event of all time. Called the end-Permian
event, the extinction saw over 90% of species perish. Thought the causes of the event are still debated,
the event seems to have been a case of runaway climate change kickstarted by flood basalt eruptions in



"Jurassic World"'s really BAD science! (DVD) Commentary by Paige Elsea

A new theme park, built on the original site of Jurassic Park, creates a genetically modified hybrid dinosaur, which escapes containment and goes on a killing spree.
Just a bad geology movie! Time will be opened up after the movie for discussion and debate over this movie and its bad geology/paleontology.








The purpose of Geodeland Earth Science Clubs, Inc. is to organize, promote, and conduct a cooperative educational Gem and Mineral Show, located in Macomb, Illinois. This group consists of several gem and mineral clubs located within central Illinois.

The annual GESCI Gem & Mineral show in Macomb Illinois is located at the Student Union on the campus of Western Illinois University.

To keep interesting and fresh, we update our site design and content every year!
