What wasn't preserved was any proteins or fats or body fossils
that would clinch the case for life and identify what types of bacteria left behind this organic carbon.
When scientists combine what they learn from body fossils
with clues they find in trace fossils, they can get a clearer picture of the ancient world.
Trace fossils are an important element of the Cambrian faunal record, particularly in siliciclastic sediments where body fossils
generally are scarce.
Video monitors begin by briefing the guests about a fictional Centre for Advanced Palaeontological Research, which was formed to bring dinosaur tracks and body fossils
together for the first time.
Most researchers have focused on the body fossils
of the Burgess Shale," said study co-author Gabriela Mngano.
For the first time, dinosaur tracks and body fossils
were discovered together, opening up amazing new research possibilities.
