Question

how were trace fossils created in the past? they traced their foot with a pencil pressed into cement pressed into a rock in wet/soft soil rewatch skip

Explanation:

Trace fossils (like footprints) in the past were formed when organisms left traces in wet/soft soil. Over time, the soil hardened or sediment covered it, preserving the trace. The other options (tracing with pencil, pressing into cement/rock) are modern or non - natural processes for creating imprints, not how ancient trace fossils formed.

Answer:

in wet/soft soil
