| Explain the signor-Lipps Effect |
|
Definition
| A sudden mass extinction such as a meteor hitting will never appear sudden in the fossil record. Therefore criticism of saying that dinosaurs died out before the mass extinction because the most recent dinosaur bone was found before the K/T barrier is wrong. Using a system of a 50% confidence interval we can see that because the bone was found at the 3 meter interval when the intervals generally come in sets of 5 meters, so there is a system that is set in place that determines more appropriately when a species died out according to the 5 meter intervals. |
|
|
Term
| Given data be able to calculate a 50% confidence interval and use it properly. |
|
Definition
| The lowest meter is the most recently found. Take this amount and move up the confidence interval, which is the median. This gives you a graph that tells you if the species died out before, because of, or after a major extinction event. |

Term
| What is evidence for a bolide (Meteor/extraterrestrial) impact at the K/T Boundary? Give 2 Examples |
|
Definition
| 1.) There was an unusually high amount of iridium at the earth’s surface. High concentrations of iridium were found in the boundary clay in sites all over the world, indicating a global event. 2.) Mineral quarts called shocked quarts were found in boundary sediments. Shocked quarts has only been observed in meteor craters and nuclear weapon test sites. |
