When you deal in millions of years, a few days are relatively insignificant.

That’s why Sternberg Museum is observing National Fossil Day on Saturday rather than the more traditionally recognized day of Oct. 14.

“We’re doing things a little differently this year compared to the past few years by celebrating on a Saturday rather than Wednesday,” Sternberg curator of paleontology Laura Wilson said.

But, she was quick to add, it’s still a free day of admission to the museum for everyone.

Special programming is planned from 10 a.m. to 5 p.m.

“We will have scientists with special displays set up around the museum that explore the fossil history of Kansas,” Wilson said in announcing the early observance of National Fossil Day.

Those displays will look at why animals have the color patterns they do, how plants and animals adapt to different environments and how tracks and traces are made.

Portions of the research collection that normally aren’t on display will be available, and there will be live animals and fossils that can be touched.

Arts and crafts also will be available and the Discovery Room will be open.

The museum will be open from 9 a.m. to 6 p.m.
