Question

which sources would preserve the soft tissues of an early mammal? check all that apply. amber in russia frozen soil in the arctic shale in virginia sandstone in the badlands foraminifera in the ocean ice sheets in greenland

Explanation:

Amber can preserve soft - tissues well due to its ability to quickly encase and protect organic material. Frozen soil in the Arctic can also preserve soft - tissues through cold preservation, slowing down decomposition. Ice sheets in Greenland are not typically known for preserving soft - tissues of early mammals as they are more associated with glacial processes rather than soft - tissue preservation. Foraminifera in the ocean are single - celled organisms and not a source for preserving mammal soft - tissues. Sandstone in the Badlands and shale in Virginia are sedimentary rocks that are not ideal for preserving soft - tissues compared to amber and frozen soil.

Answer:

amber in Russia, frozen soil in the Arctic
