"We just don't have very much fossil evidence on early humans in Europe," Dr. Smith said.

No fossil evidence has been discovered for ultramicroscopic intracellular replicators such as viruses.

No fossil evidence yet exists for viruses.

Paleontologists say they have found the first compelling fossil evidence that long ago, snakes grew legs.

The putative fossil evidence occurs on surfaces of cracks within the rock.

Little fossil evidence is available to help map the evolution of bats, since their small, delicate skeletons do not fossilize very well.

The most plausible scenario, and that which best fits the scant fossil evidence, is this:

There's fossil evidence of humans appearing in Central Asia around this time.

The available fossil evidence indicates both the hominoid and cercopithecoid clades originated in Africa.

Lambdopsalis even provides direct fossil evidence of mammalian fur in a fairly good state of preservation for a 60-million-year-old animal.
