Fossils B/C

[thecranberry]

How do you distinguish between an allosaurus and a tyrannosaurus just by looking at them?

Okay, so the Allosaurus has the "horns" -extensions of the lacrimal bones- above their eyes. Not the best example, but bit like this smiley:
Pretty cool, I think.

How do u guys distinguish between a deinonychus, coelophysis. and a velociraptor.

Also, are the tests progressively harder as u go from regionals to state to nationals?

yes, this what is supposed to happen as you advanced from each level of competition, as for identifying the three fossils is best said by one age [Colephysis was well before the other two] then Deinonychus finally Velicuraptor. Deinonychus has a claw that it uses to kill with. Coelophysis is the smallest of the three, Also velocuraptor is not nearly as large as how it is pictured in 'Jurassic Park' don’t let that confuse you with the real fossil. Wikipedia/ Google search it some to so you can identify between them.

Keep pictures of every dinosaur skeleton, skull, and a "picture" of each genus in your binder. That way, you'll be able to tell what it is no matter what they throw at you (hopefully). The skulls are each different, so that's a good place to start. Coelophysis's skull is long, thin, and curves downward. Deinonychus's skull is broader and flatter. Velociraptor's skull curves slightly upward, and is smaller than Deinonychus.

The test are supposed to be progressively harder, yes, but that is not always the case.

Yes, the tests are supposed to get harder as the event level goes up. If it didn't, you would end up with cindarella storys in nationals.

Look at the skulls of each closely, taking care to view a good number of different specimens. You will begin to see things that are fairly indicative of each. The size of each is different if there is a reference. The deinonychus generally has a bulkier build, of the skull and body. Velociraptor has a pronounced bump at the end of the snout.

Usually tests at higher levels of competition tend to be harder, but don't take this as meaning that there is no way that you would get an insanely difficult test at regionals or an incredibly easy test at nationals. I have experienced both, they happen, and unfortunately such things are really not that uncommon. Always prepare for the harder test, you'll do better on that one when and if it comes and you will do better on the easier tests too.

How much information does anyone have for each group of fossil [like for Trilobites, Coral ect] it says in the rules that basic information/ adaptations for each group. How much in depth have people gone to put information into the 3Ring Binder?

As in depth as u can get i suppose...but more importantly, try to understand ur binder. Know where everything is, have a feel for where ull need to look for a certain piece of info...

A good thing that I've learned from over the years on binder events is to make a binder and then go through EVERY SINGLE genus/species on the list and literally type up an information page from scratch for each. It takes forever but it pays off, not to mention it really helps you with your identification.

deeisenberg already answered this question in detail earlier in the forum. Why cant people read the whole forum before posting?
