Mass Extinction
Not fish
This cause of mass extinctions come from space and lead to dramatic climate changes.
asteroid strike
True or False: Relative Dating determines the exact age of a fossil.
False
What are "Mega Fauna"?
Large Animals
This animal went extinct about 10,00 years ago, was the size of a Volkswagon Bug, the ancestor of the modern armadillo, and went extinction because of human predation.
Glyptodon
There have been two mass extinctions that eliminated dinosaurs. Name one of them.
Jurassic/Cretaceous or Triassic
This cause of extinction is when the homes of animals are dramatically changed or destroyed.
Habitat Loss
"Fish came before reptiles in this environment. We know this because the fish fossils are found deeper in the rock than the reptile fossils."
Yes (or true)
Pangea
This mega fauna went extinct about 11,000 years ago, was hunted to extinction by humans, and is survived by a slow tree dwelling creature of the same name with two or three toes.
Giant Ground Sloth
The asteroid that ended the Cretaceous period landed near what modern country?
Mexico
This cause of extinction is when a new animal is introduced to an environment where it doesn't belong. An example would be the Burmese Python in the Everglades.
Invasive Species
Is this an example of relative dating?
"Mr. D is 12 years older than his students."
No (or false)
Vertebrate animals must have a ______.
Backbone or spine
This sea creature seemed to go extinct during every early mass extinction. They had a hard shell, legs like a crab, a rounded top like a horseshoe crab, and were one of the earliest animals
Trilobite
For a mass extinction to take place, ____% to ____% of all animals must go extinct
75%, 90%
This type of cause of extinction is having a profound affect on ocean populations. One example would be plastic bags being swallowed by sea turtles.
Pollution
What type of rocks are fossils found in?
Sedimentary Rocks
What does "ocean anexia" mean?
Lack of oxygen
This animal was one of the first flighted dinosaurs, went extinct about 130 million years ago, and lived in southern Germany.
Archaeopteryx
What mass extinction had the biggest drop in animal populations?
Permian Extinction
This cause of extinction results when a species has a shallow gene pool. One example would be cheetah.
Genetic Diversity
Absolute Dating determines the exact age of rocks. What kind of rocks can be absolutely dated?
Igneous
Gondwana was a combination of what two continents?
South America and Africa
This organism was a strange mammal-reptile hybrid whose fossils have been found in Africa, South America, India, and Antarctica. Their cause of extinction was hard to find.
