SPRINGFIELD (AP) – The Missouri Institute of Natural Science will be able to double its size after receiving an anonymous local donation.

The Springfield News-Leader reports that the donation will cover a significant portion of the museum’s expansion, which will cost about $170,000. Bob Lawrie, a museum board member, says that the expansion will include a lower-level bone preparation room where visitors can see fossils being readied for display, an observation deck and a gift shop with fossils for sale.

The expansion will provide room for hundreds of fossils, including the famous “Henry” triceratops.

Recently, a South Dakota fossil collector donated two truckloads of prehistoric fish, crocodiles, mammal skulls and teeth, according to museum director Matt Forir.

The museum is not disclosing the amount of the donation at this time, but Lawrie says they still need donations from the public.
