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 traps organisms quickly, creating an oxygen-free environment that prevents decomposition of soft tissues.
• Frozen Arctic soil and Greenland ice sheets maintain extremely cold temperatures that slow or halt decay processes, preserving soft tissues over long periods.
• Shale, sandstone, and foraminifera deposits typically preserve hard parts (like bones or shells) rather than soft tissues, as they involve sedimentary compression or mineralization that does not protect soft organic material.

Answer:

A. amber in Russia
B. frozen soil in the Arctic
F. ice sheets in Greenland
