1. Identify these specimens A and B.
2. What material are each of the specimens preserved in?
3. What are tagmata?
4. What ability has made members of the taxon of specimen A so successful? Explain the two different mechanisms/physiologies that can enable this ability.

1. Insecta, Crustacea
2. amber, mudstone
3. Groupings of segments (e.g. head, thorax, abdomen)
4. Flight, direct flight: muscles attached directly to wings, indirect flight: muscles move thorax (in turn moving the wings)

Given two similar looking fossils, list how you would distinguish them:
1. Allosaurus vs. Tyrannosaurus (you're only given the skull so size is not an option)
2. Equus vs. Mesohippus (you're not given a picture of their feet)
3. Mammut vs. Mammuthus
4. Exogyra vs. Gryphaea
5. Acer vs. Platanus

4. Exogyra vs. Gryphaea
5. Acer vs. Platanus
[hide]1. the Allosaurus skull is typically narrower, and they have more prominent little horn thingies over their eyes (haha very scientifically stated ik) 2. Mesohippus have smaller teeth if you're given the teeth (which is typically the case for actual specimens)
3. If you're given a picture of just the skeleton you can look at the tusks, Mammut has less curved ones typically. Mammuthus also has a big ol' tuft of hair on its head if you're given a drawing.
4. Exogyra is typically bumpier, but Gryphaea has these lined layers. A good way is to also look at the valves because Exogyra has this whole left/right valve thing where the right valve is flat and small, but the left valve is the opposite.
5. I think usually the Platanus leaves start to grow out closer to the bottom of the stem also sometimes Acer has these little leaves that grow out at like a 180 degree angle towards the stem bottom, but when Platanus has that, they're longer. (sorry if that description sucks a lot)[/hide]

For #4 I was thinking more of the whole devil's toenail thing for Gryphaea, but that works also.thanks for adding to my binder hehehehe
