New Mexico gets a look at first-of-its kind fossil

Paleontologists in New Mexico have showed the first baby Pentaceratops skull ever discovered. Hundreds of people lined up to get a look.
Scientists cut open a giant plaster jacket. It protected the skull of the rhinoceros-like, plant-eating dinosaur. This was done as it was airlifted out of the desert badlands of northwestern New Mexico. Then it was trucked to the New Mexico Museum of Natural History and Science.
They revealed the shield-like part of the dinosaur's skull. They also revealed some teeth, an arm bone and a rib. And, what looked like a vertebrae. But museum curator Spencer Lucas said there is still much work to be done.
Technicians will begin the hard work of digging out the fossils from rock. The fossils have been encased for some 70 million years.
The process will take months. The public will be able to watch. Windows will offer a view into the museum's preparation room.
On Nov. 5, hundreds of people lined up along the windows during a free public viewing. Among the viewers were parents with their children. Some children got an up-close look. The museum staff showed off the find. Other visitors held up their smartphones on the other side of the glass.
Lucas said the fossils are important. He said they were sure to give new insight into the dinosaurs that roamed North America. They lived tens of millions of years ago. Less than 10 adult Pentaceratops skulls have been unearthed over the past century. This marks the first baby skull to ever be recovered, Lucas said.
"So here now we have the first glimpse at growth and the early stages of life of this dinosaur," he said.
Experts say Pentaceratops was one of the largest horned dinosaurs that ever lived. It may have even been the largest. It could be up to 27 feet long and weigh 5 tons or more.
Paleontologists think Pentaceratops may have used its five horns for defense. Evidence also suggests the horns and the shield-like part of the skull could have been used to attract mates.
The remains of the young Pentaceratops appear to have been washed through a streambed. Some of the skeleton has fallen apart. But how the animal died is being investigated, scientists said.
Muddy conditions kept the team from moving the plaster jacket that contains the remainder of the baby's skeleton. That will happen later.
The discovery was made in 2011. It was made in the Bisti Wilderness by Amanda Cantrell. She is the museum's geoscience collections manager. A few years of planning, permitting and excavation followed with the help of New Mexico National Guard Blackhawk helicopters.
Pilot Kevin Doo attended the unveiling. He was with his wife and child. He said it was amazing to see the prized cargo unwrapped.
"What a terrific find," he said. Doo noted that a lot of hard work went into pulling off the unique recovery mission.
A crew of museum staff and volunteers also had to pack in tons of tools, water, plaster and other materials to prepare the fossils for removal. That is because the find was made within a federally protected wilderness area.
