Does anyone have any tips on how to better teeth ID? We always seem to struggle with them on tests and I wanted to know if anyone has any tips on how I could identify them with more accuracy
Thanks!
I also suck at teeth ID as well, but i'm actually not too bad at it. I mean, I accidentally confused Human teeth with horse teeth because i don't think I was thinking straight at comp and partner did not correct me, but now that I look at the test a second time, it looks more like the stuff that I know, human teeth
Which teeth are you referring to?
If it's Otodus and Carcharocles, then look for medium-small "ears", carcharocles don't have these at all, but if they do, they'll probably really small poking out of the root of the tooth
If it's a Basilosaurus, it has multiple "ears"
If it's a fish-tetrapod creature (acanthostega), it has relatively small teeth, but there are many, and the bigger teeth tend to be at the front of the mouth
If it's a Eryops, then the tooth will be really interesting, they are medium sized, and are sometimes curved a little, just search it up
Crocodile teeth can be as long as Eryops, but many are short and stubby, and the teeth are smoother
Ichthyosaur teeth are hard to describe, but I can tell the difference between these teeth and other animals teeth
Mosasaur, you probably know this, but they are usually brown and have a large width, having like a white-ish root
Pliosaurs, teeth are more defined in their ridges than ichthyosaurs, white-ish root thing (I usually see these a lot on tests)
Plesiosaurs, teeth are less defined than pliosaurs, pretty smooth, reminds me of skinny mosasaur teeth
Pterosaurs/Pterodactyl: yikes, it's so similar to pliosaur/plesiosaur teeth and has less ridges, often being black or brown, the weird thing is that some of the pterosaur teeth that I've seen have a heart shaped top of the tooth (you'll see when you search it up), it's relatively smooth on the tip of the tooth and has ridges closer to the base of the tooth
Allosaurus: black teeth, has a couple of ridges, white crevasses, not too curved inward, kinda remind me of their claws
Coelophysis: white/brown, small teeth, but could grow up to half inch, REALLY smooth, back of tooth has like "striations",some of the remind me of fingernails
Dilophosaurus: black, can be found in a group, skinnier than allosaurus teeth and elongated
Spinosaurus: Never seen one on a test, but they are golden-brown, I would even say this, that it's a combination of a pliosaur tooth and allosaurus teeth
Tyrannosaurus: Well... for a giant carnivore, what can you expect from Tyrannosaurus, apparently they might have had serrated teeth? It's kinda hard to describe this one. But, its Tyrannosaurus, what can you say? Kinda similar to Carcharodontosaurus though
Velociraptor: serrated teeth, small, brown, idk if they'll test this, but they test the claws
Brachiosaurus: well, it at ginkgos, so it did not have serrated edges, instead having chisel-shaped, i looked at pictures, and most of them are black and to me, they resemble black ovals
Diplodocus: ouch this is conflicting, I doubt it had long teeth, so I would say that it is pretty similar to brachiosaurus, and are longer I would say, and less circular
Patagotitan: similar to brachiosaurus, except they are kinda long and brown, you can see the teeth if you have a picture of patagotitan in your binder
Dimetrodon: kinda tear-drop shaped, serrated
Humans : you should know already, you probably look at your teeth everyday
Equus: look at the top of the tooth, where it has like four square things and odd designs
Mesohippus: also look at the top of the teeth, consistent designs
Smilodon: two big teeth that were maybe used for slicing
Mammut vs Mammuthus, easy, you probably know this already, but here's the difference
Mammuthus: a solid tooth, with crevices/striations along the side
Mammut: many little teeth grouped together as a whole
Brontothere/Megacerops/Rhinoceros like thing : a really smooth top, the teeth are like v-shaped from the side view, top is black, the root? is white, and there is some white stuff on their teeth that I have no clue what it is, I think it's the enamel?
Sorry! I was rushing! It's hard to describe teeth. I am not a professional dentist
If you want to make more accuracy, just add an index for teeth in your binder... It's really hard to get them down
also try to predict what you think your proctor will think so then you know what to study, hahaaaa I did that two weeks before comp, and what I predicted was correct for Meteo (predicted a Skew-T, and my goodness it was on there, and I was so angry) and Fossils (predicted anatomy (it kinda turned out that the proctor kinda liked putting questions about Anatomy), cladistics)
Fossils predictions: always think anatomy, ancient climates, extinctions, also try thinking about bio, cause I believe that's more common on Div C than Div B
ALso, my friend who is in ornithology took an ornithology test yesterday, then asked me today "what is a lagerstatten?" she said that both she and her partner were super confused lol She then showed me the test question "Identify the two subspecies of this bird and what lagerstatten would this bird be found at" and i said "La Brea Tar pits, a lagerstatten is a place with extreme preservation and variety"
Do you ever think that they'll ask any questions like that for Ornithology Division B? It's really strange how test creators like to mash up events into each other. I saw an anatomy question on a crime busters test and my old DP partner said that there was an oceanography diagram on one of the WQ tests...
