They created 3D reconstructions of any fossils inside, which included a handful of octopus jaws, the only hard part in these soft-bodied creatures.
The jaws allowed an estimation of the animal's body size, and they were likely colossal, each one larger than a school bus.

Just a few fossil findings may shed very new light on the evolution of the biosphere.
The results paint a vivid picture of the ocean ecosystem of the late Cretaceous, one that would have been filled with a variety of large and hungry predators.
A team of scientists sliced through large rocks that had formed on the seafloor 100 million years ago.

A team of researchers wondered whether malaria, a longtime lethal disease carried by mosquitoes, may have influenced where early humans lived.
So they took a set of climate models spanning the last 74,000 years, overlaid where mosquitoes would have lived, and compared that to where people were, based on archaeological evidence.
The result was clear, says University of Cambridge evolutionary ecologist Andrea Manica.
Then, some 15,000 years ago, when the sickle cell anemia mutation arose, which can offer protection against malaria, people's avoidance of the regions with the disease began to break down.
