Summary Introduction
Introduction: Dating is a technique used in archeology for ascertaining the fossil's age, artifacts, and some precious items. It can be classified into two broad categories, including absolute and relative dating.

You look at a microfossil under a scanning electron microscope and it is the same shape as a cell. b. A high-quality transmission electron micrograph of a fossil cell reveals cellular compartments, including a possible nucleus. c. Potassium dating of a fossil containing a possible cell indicates that the fossil is 3.2 billion years old. d. Using transmission and scanning electron microscopy, you find evidence of a carbon-based material in what appears to be a cell wall of a fossil isotopically dated as 3.2 billion years old.arrow_forward

- In radiometric dating, scientists use the half-life of a radioactive isotope, to determine the approximate age of rocks, and the fossils that are embedded in them. Half-life is the time it takes for half of a radioactive element to become stable.Uranium 238 (238U) is a radioactive element that decays into Lead (206Pb) after 4.5 billion years. 6) Scientists found a fossil in a layer of rock that tested as 1/8th U and 7/8th Pb. What is the approximate age of the fossil? A) 562 million years old B) 4.5 billion years old C) 9 billion years old D) 13.5 billion years old Not Gradedarrow_forwardWhat kinds of tool artifacts were found in the cave near Denisovan specimens? A. Lithic cores B. Levallois cores C. Oldowan Choppers D. Both A and B E. Both A and Carrow_forwardOrganism A lived from 410 to 60 million years ago. Organism B lived from 200 to 100 million years ago. Which organism will be the better index fossil? (1)arrow_forward
- Radioisotopes are useful in dating fossils and rocks because a. they are present in very high amounts. b. they decay rapidly. c. they decay in a predictable pattern over long time period. d. their rate of decay changes over time.arrow_forwardWhy are indices better than simple measurements for comparing fossil specimensarrow_forwardA. How old is the Earth? B. How long did the longest eon (so far) last? C. How many years ago did the most recent epoch begin? D.
