Clues to what ancient climates were like come from all of the following except a. fossil trees. b. very old weather records. c. fossil tree rings. d. ancient plant pollen. make sure you know what u talking about too

The answer is b. very old weather records.

Fossils represent remains of organism from the past. Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue. Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
Fossil tree rings, fossil trees, and fossil plant pollen are usually well preserved and can represent ancient climates. By knowing what kind of trees had lived in some past period and how they had pollinated can explain what climate were in that period.

Clues to what ancient climates were like come from all of the following (fossil trees, fossil tree rings, and ancient plant pollen) except b) very old weather records.
