Many fossils of the other creatures, such as ancient elephants and rhinos, have been dated before at other locations using the volcanic ash, potassium-argon method described above.

If dated fossil are found near the hominid bones it can be said that both species lived around the same time, and hence the homonids samples can be dated. t very good for very old specimens; fossils were often found with no volcanic deposits present; and the use of other fossils such as ancient hyenas or antelope wasn’t always so reliable for pinpoint dating because the animals often they lived for a long time on the evolutionary timeline.

Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions.

A fossil only becomes a fossil when it has reached a certain age.

Each volcanic eruption has a unique "fingerprint" and sometimes they scatter ash over a vast area.

In analyzing the other fossils found around the newly discovered hominid bones.Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.Fossils are found all over the world and on every continent.A paleontologist is a scientist that studies fossils.The International Commission on Stratigraphy revises the timescale annually.
