DALLAS (AP) - On the five public floors of the Perot Museum of Nature and Science, visitors can view 396 specimens of preserved animals and dinosaur bones.

But there are another 117,703 museum artifacts they can’t see, and - with few exceptions - never will.

The Dallas Morning News (http://bit.ly/1p1nAcG ) reports while the items include some books and artwork, the vast majority are animals - fossil remains from eons past and preserved specimens of animals that still walk the earth, said Karen Morton, the collections manager.

Morton is in charge of cataloging and housing the specimens at three sites in Dallas: the old museum facilities in Fair Park, the basement of the new museum and an unmarked warehouse near the Dallas Design District.

There, almost every square foot of the floor, walls and shelves is crowded.

If you’re thinking of donating grandpa’s stuffed deer head in the attic, don’t.

“We’re full. The rooms are full,” Morton said. “Really, we don’t have space for anything more.”

The stuffed specimens range from an extinct passenger pigeon to the we-only-wish-they-were-extinct grackle.

“Our mission is to preserve the diversity of all Texas wildlife,” said Ron Tykoski, who also manages the collection, explaining why someone would safeguard a dead grackle.

The rows of stuffed birds and predators represent an earlier era in natural history museums. Since the 1970s, museum visitors and staff are more likely to be interested in a pachyrhinosaurus skeleton than in a stuffed polar bear.

Tykoski, a staff paleontologist, said the specimens - though unlikely to be exhibited in the museum’s public spaces - are an important part of the Perot’s scientific mission.

In fact, that importance has recently grown.

“At one time, these were considered white elephants. Museums were chucking them away,” Tykoski said. “But scientists have found that even taxidermied animals retain some genetic material that can be used for research.”

Retaining multiple examples of a species - the collection has 508 warbler specimens - allows researchers to study variations within a population. The range of decades represented among the collection’s specimens also ensures that some came from habitats that have long since vanished.

“We’re caretakers of research resources,” Tykoski said. “They’ve lasted for decades, and we have to see they last for decades more.”
