Question

Hi, can you help me with this question for my evolution class? There's two paper for that question. So I tried to post this question as together as possible.

Problem 1 (20 pts). In an estuary in the PNhe larges discovered a new set of fossils from a close relative of ta known bird. Their wings are huge, spanning 3.8m (-12 /Name: Pacific Northivest, youh atorns the larges ft). 5 iii. Calculate upper and lower bounds would you put on the age of terratorn fossils in the following layers. You have found terratorn You can say 'None' to indicate that a particular upper or lower age limit cannot be determined. For example: if based on available evidence you could limit the age of a layer to between 1-2 bilion years ago, you would write 1 billion' in Min and '2 billion' in Max. Don't guess, just write the minimum and maximum dates that you can prove from the available Ssils in strata C, D, and E. marked with bird skulis) You use a combination of stratigraphy and radioisotope dating to establish the age of your fossils evidence, and the principies of stratigraphy Minimum Age: Maximum Age: Two layers of shells, Shell layer 1 and Shell layer 2 Layer C Explain Shell Layer 2 provide plenty of material for radiocarbon dating Max Layer D Min: Explain: In Shell Layer 1, the shells contain 25% Carbon-14 and 75% Nitrogen-14. The radioactive decay of carbon-14 to nitogen-14 has a half-life of 5,730 years. Given this data, what is your best estimate for the age of Shell Layer 1? i, 5 Layer E Min: Explain: Max: iv. Which is older, the terratorn fossil from stratum C or the one from stratum D? ii. In Shell Layer 2, the shells contain 14.5% Carbon-14 and 85.5% Nitrogen. 14. What is your best estimate for the age of Shell Layer 2? Circle one a) Stratum C fossil s older than the Stratum D fossil b) Stratum D fossil is older than the Stratum C fossil c) The fossils in Stratum C and D are the same age d) Can't Tel Hint: You probably don't need a calculator for part i (other than maybe for some simple multiplication). You will need one for part i, but should have a pretty close estimate of the correct number before you do the calculation.

Explanation / Answer

Question IV

stratum D is older than stratum C fossils

The upper rocks are younger and the underground rocks are older.

Question I

shell Layer 1 age is approximately- 11500 years

Question No II

shell Layer 2 age is approximately - 16000 years approximately

Question No III

Layer C

Min 11500 Max 13000 years

Layer D

Min 13000 years Max 16000 years

Layer E

Min 16000 years Max 18000 years
