    Trace fossils most often were created in soft sediments, and are usually preserved only if the sediment remains undisturbed until it has become rock. Trace fossils have been found in rocks as far back as the Late Precambrian. First known fossil occurrence: Precambrian. Last known fossil occurrence: Quaternary. This group has living relatives.

Showdown on the Burgess Shale - by Simon Conway Morris and Stephen Jay Gould.

    The “Cambrian Explosion” refers to the appearance in the fossil record of most major animal body plans about million years ago. The new fossils appear in an interval of 20 million years or less. On evolutionary time scales, 20 million years is a rapid burst that appears to be inconsistent with the gradual pace of evolutionary change. A Collection of Cambrian Fossils When you're standing in a museum surrounded by fossils, you can almost imagine drifting through time to when long-extinct creatures swam the ocean. Found all over the world, these fossils can be read by scientists like pages from the book of the past.

    Cambrian localities on this server: (see map above) Aldan River - Lower Cambrian fauna from this site in Yakutia, Siberia, trace the early evolution of animals with skeletons. Burgess Shale - One of the greatest fossil finds ever made is the Burgess fauna of British Columbia. Thousands of soft-bodied animal fossils paint us a picture of early. The increase in trace fossil diversity across the Neoproterozoic-Cambrian boundary often is presented in terms of tabulations of ichnogenera. However, a clearer picture of the increase in diversity and complexity can be reached by combining trace fossils into broad groups defined both on morphology and by:

A trace fossil, also ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity but not the preserved remains of the plant or animal itself.

Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or mineralization. Other trace fossils that first appear at approximately this level are trace fossils with a three-lobed lower surface (see Jensen and Grant, ).

The chances of finding similar fossils elsewhere seemed slim, but nevertheless in the 's and 90's troves of Cambrian fossils were uncovered in several locations in Yunnan Province in China.
