Re: Fossils B/C
1. What does a “coal gap” in the fossil record following the Permian extinction suggest?
2. Why did “meandering” streams change to “braided” streams after the Permian extinction?
3. What organism temporarily replaced reefs after the Permian extinction?

Re: Fossils B/C
1. The Coal gap in the fossil record suggest a lack of coal-forming plants. This lack of plants could have been from the losses of the Permian extinction itself, or new environmental conditions that affected the plants. 2. Meandering steams changed to braided streams following the change in climate from the End-Permian extinction to the early Jurassic. The landscape became very dry and a lot of vegetation was lost, which allowed the streams to become braided. 3. Bivalves became the reef builders. In specific, Rudists.

Re: Fossils B/C
Number 3 should be stromatolites, which took over when corals died. Rudists appeared later on. Other than that looks good. Your turn!ChimpLopez wrote: ↑January 27th, 2020, 5:48 am1.

Re: Fossils B/C
Might be a little easy but here goes :/
1. Identify the this organism?
2. Where and when was this specimen discovered?
3. What is the significance of the discovery of this specimen?
4. Name some characteristics of this specimen that links it to modern tetra pods.

Re: Fossils B/C
Answer these questions about Titanis
1. What time period did Titanis live in?
2. T/F? Unlike most other birds, the bones of Titanis skulls are completely fused together
3. Give two possible theories of how Titanis killed its prey
4. What are the closest living relatives to Titanis today?
5. The earliest Titanis fossils found was in Texas dating back 5 million years ago. Why would this be considered unusual?
6. What type of habitat did Titanus inhabit?
7. What other predators did Titanus compete with?
8. Why did Titanus die out during the Pleistocene era?
