That statement is incorrect. Metamorphic rocks are formed by the transformation of pre-existing rocks through intense heat and pressure. They do not contain any biological material or record of biological time.
However, a record of biological time can be found in sedimentary rocks. Sedimentary rocks are formed from the accumulation and lithification of sediments, which may include organic remains such as fossils. Fossils contained within sedimentary rocks can provide valuable information about the past life forms and the time frames in which they existed.
