Limestone.
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
Ripple marks likely indicate that a rock formed in a sedimentary environment, such as near a shoreline or in a river bed, where the movement of water created the distinct ripple pattern in the sediment before it hardened into rock. These marks provide information about the ancient depositional environment and the direction of water flow at the time of formation.
You would most likely find fossils in sedimentary rock. Sedimentary rocks are formed from layers of sediment that accumulate over time, which can help preserve fossils in the rock.
precipitation from seawater
The rock is most likely sedimentary. Sedimentary rocks are typically formed from the accumulation and compression of sediments, such as sand or clay, over time. These rocks often exhibit layering due to the different materials that have settled and compacted together.

A red bed indicates that the sedimentary rock was likely formed under oxidizing conditions, where iron minerals were exposed to oxygen, causing them to rust and turn red. This suggests that the environment was well-aerated and had abundant oxygen at the time of deposition.
The scientists are most likely examining sedimentary rock, as fossils are typically found preserved within this type of rock. Sedimentary rocks form from the accumulation of sediments over time, which can provide an ideal environment for preserving fossils.
Metamorphic
rocky
Sedimentary rocks, such as sandstone, shale, or conglomerate, are likely to be found in an ancient riverbed on the Earth's surface. These rocks are formed from the accumulation and compaction of sediments carried by rivers over time.
A dried-up lake bed would most likely produce sedimentary rocks as the sediments from the lake would settle and be compacted over time. Sedimentary rocks are formed from the accumulation and compression of sediments. On the side of a volcano, you would expect more volcanic and igneous rocks to form from the volcanic activity.
