Enormous fossils of crocodiles, a prehistoric elephant and a giant tortoise that were found in the 1970s and 1980s are being studied anew. The fossils were too large to safely move at the time of their discovery, so the researchers — including members of the Leakey family, famed for their paleontology research, along with colleagues — left them in northern Kenya's Lake Turkana Basin. Now, decades later, paleontologist Louise Leaky and her colleagues have returned to the site and captured digital 3D images of the fossils, so researchers everywhere can study the animals' remains.

Here is a look at their work:
Crocodile scan

Busted crocodile
A 1.8 million year-old crocodile skull gets 3D scanned by Denis Baev, the head of the product requirements department at Artec. Such scanning records the details and dimensions of fossils. It's likely that people had vandalized and broken the crocodile fossil since the Leakey team uncovered it decades ago, he said. (Photo credit: Artec Group)

Giant turtle
Leakey and Baev scan the fossilized shell of a giant tortoise. It took them about two hours to scan the shell because they had to scan both the inside and outside to record all of its details, Baev said. (Photo credit: Artec Group)
Elephant tusks
Discovered in 1974, this prehistoric elephant (Elephas recki) is larger than its modern ancestor, the Asian elephant. The fossil includes the elephant's skull, tusks, mandible, limb bones, ribs, vertebrae and foot bones. (Photo credit: Artec Group)
Safe haven
The Leakey family and their colleagues built enclosures around some of the fossils that were too large to safely move to a museum. Now that researchers have scanned the fossils in 3D with special tools, the Leakey family may move the fragile remains to a museum or research institute for safekeeping. (Photo credit: Artec Group)
Creepy insects
During the researchers' trip, giant insects emerged at night. Baev called them the worst part of the trip to Kenya. The insects would flock to any light source, be it a computer monitor, scanner, cellphone or flashlight. He said he always cheered for the bats, which would eat the insects.

Hominid head
Once back at the Turkana Research Institute, the researchers also created digital images of casts of hominid skulls kept there, with the 3D scanners. (Photo credit: Artec Group)
