Displays

Paul Mayer, Invertebrate Collection Manager at the Field Museum, had a nice trilobite display.

The Lizzadro Museum brought in part of Sylvia Josefek “Rock Cafe” display. Sylvia and her husband Paul were very active in ESCONI during 1980s and 1990s. She created and later donated this “Rock Cafe” display to the Lizzadro Museum in Oak Brook, IL. (see Throwback Thursday #287)

Burpee Museum brought in a cast of Jane’s skull. Jane is a Nanotyrannus lethaeus on display at the Burpee.

Jack Wittry brought a display of shark teeth. Look at those amazing Megalodon and Edestus teeth!

And, minerals of Michigan’s Iron Range.
