We are having a party this week! The Chicago Academy of Sciences was founded on January 13, 1857 and was the first science museum in Chicago. Our collections served as the nucleus for the organization of our institution and preserve our natural heritage. These specimens, artifacts, and associated documents are used as primary source material for environmental studies and historical research. To celebrate our birthday, we’ve brought out specimens from the museum collections that aren’t typically on display.
One question we are often asked is, “What is the oldest specimen in our collection?” The oldest specimen in our museum collection, in terms of when it was collected, are two Merlins collected in the Rocky Mountains in 1834 by J.R. Townsend. That’s right — bird specimens that are 182 years old! One of these is on display.

Fossils, though, have the award for oldest in terms of when they were created! This “Tully Monster” fossil is from the Mazon Creek area, right here in Illinois, and is approximately 307 million years old.
Tully Monster
(Tullimonstrom gregarium)
Mazon Creek Area, Will Co., Illinois
Francis Creek Shale (Carboniferous, 307 MYA)
Donated by Earth Science Club of Illinois, 2013
CAS 2013.3.1
The Academy’s museum collection includes spectacular geology specimens from the Midwest and locations across North America. These specimens help illustrate how rocks and minerals are used in our society.
Rivers in Illinois have changed considerably over the last 200 years and pollution has severely impacted many native species of clams, mussels, and snails. Introduced species, such as Quagga and Zebra mussels, are making an appearance in our waters as well.

This plant specimen from our botanic collection was collected by Floyd Swink, a prominent botanist who co-authored “Plants of the Chicago Region.” In 2013, Gerould Wilhelm, Swink’s coauthor, visited our collections facility to review some of our plant specimens and annotated several, including this one. These “conversations” left by researchers who utilize our collection adds to the scientific knowledge of those specimens.
Parlin’s Pussytoes

Palos Park, Cook Co., Illinois

Annotated by Gerould Wilhelm in 2013

Other specimens from our ornithology collection are also on display.

Steve Sullivan, our Curator of Urban Ecology, studies squirrels and manages Project Squirrel. Locally in the Chicago area, we primarily have Grey and Fox squirrels. This species is found in the Southwest.

(Sciurus aberti)
Grand Canyon, Arizona
Collected by a Park Ranger, June 1965

It is important to document species even if they’re not flashy or colorful. This one drawer of moths from our entomology collection contains species in the same subfamily, Catocalinae, that were found from across North America and span almost 80 years!

Our herpetology collection, which includes amphibians and reptiles, is largely preserved in an ethyl alcohol solution. These salamanders were collected in Indiana.

Our display is located in the Beecher Lab in Wilderness Walk hall. Come visit the Nature Museum, see these marvelous specimens in person, and help us celebrate our natural heritage!
