Maryland’s signature dinosaur, an armored browser known as a nodosaur, made the track with its back left foot 112 million years ago, Stanford said as he led an entourage of NASA officials to the print Friday morning.
Sticking out of the grass in plain view, the elephant-foot-size impression — nearly 14 inches wide — elicited gasps. “Unbelievable!” said a NASA photographer. Someone else said, “Oh, my!”
NASA officials said they accept the discovery for now as an authentic dinosaur footprint. They are moving to call in experts to confirm the find and search the area for other dinosaur calling cards.
Last week, Stanford showed the print to noted Johns Hopkins University expert David Weishampel, author of the book “Dinosaurs of the East Coast” and a consultant on the 1993 film “Jurassic Park.”
Weishampel said that the track, pressed into the bedrock undergirding the campus, is real.
“Ray showed it to me, and I was overwhelmed,” Weishampel said in a phone interview. “As a scientist, I’m skeptical of things like this. But it has all the detail you want. It’s got toe prints and sort of a heel print that’s starting to erode away.”
Added Weishampel: “It looks like a nodosaur.”
On Friday morning, Stanford pulled out a paintbrush and dabbed dirt from around the edges of the print, highlighting where he says four sharp toes once pressed into mud that eventually hardened into stone.
“These guys were like four-footed tanks,” Stanford said of the beast that left the track. Nodosaurs grew thick, spiky armor knobbed with big “nodes,” the origin of their name. They browsed vegetation and hunkered low to survive toothy attacks.
Stanford speculated that the nodosaur was running when it laid down the presumed track, possibly fleeing a predator.
“I love the paradox,” said Stanford, 74. “Space scientists walk along here, and they’re walking where this big, bungling, heavy-armored dinosaur walked maybe 110, 112 million years ago. It’s just so poetic.”
A Goddard official, Alan Binstock, said the agency considers the footprint and its location “sensitive but unclassified.”
He grew nervous as Stanford set a small plastic nodosaur inside the print for a photograph. “Maybe put the toy dinosaur away so it isn’t so obvious to people,” said Binstock, scanning for passers-by.
As Goddard’s architect and facility manager, Binstock said he would quickly move to protect the footprint. He proposed temporarily covering it and lamented that it looked as if a “big gang mower” had recently chipped its edges.
