I was trying to find the longest straight shelled cephalopod length but was unsuccessful, I heard anywhere from 7-14 feet. What's the real answer? Thanks.

General question for the group: Would you rather find a large (large being over 8 inches, in my case), inflated trilobite with some damage OR a smaller, flat trilobite with very little damage at all? I know it would depend on the actual examples, but in general I was wondering what people preferred. I have a small one that I think is cool but the larger ones are just so much more impressive to me... I am just starting to collect trilobites, as I have only recently realized they can be found in my area. Thanks.

Dinosaurs and reptiles size estimation with teeth
PetrosTrilobite posted a topic in General Fossil Discussion
Is it easy to find the size of the animal with a tooth? For example, i have a spinosaurid tooth from morroco 2.75 inch long (approx. 2 cm is root), a large mosasaur tooth about 2 inch, a Carcharodontosaurus 1.94 inch. My estimation: my spino tooth belong to an animal about 7-10 meters long if it is a of the large teeth on this spino mouth, for the carcha i think that came from the middle or the back of the jaw of an animal 5-8 meters long, and the mosasaur from a 7-8 meters long mosasaur, and is a very thick tooth. -
Good morning. Is there an accepted demarcation of what constitutes a micro? Is it 1/4 inch or smaller? These two Crows are 5/16 inches. The other photo is, I think, just a cusp which is 1/8 inch. Thanks all.

I have a question, for which there is no right or wrong answer. And I do realise that it's very personal. But when faced with choosing to buy a fossil out of a batch, and there is a fair amount of variation, how do you choose which one to go for? A smaller specimen with more detail? Or larger with less detail? I would be interested to hear opinions.

Ok here’s a question that’s been bugging me. If dinosaurs were so big why are all the teeth you see for sale so little with most being under 1”? You see T Rex teeth and there all under a inch. i would think they have teeth like a banana.

Hey guys, I recently got a bunch of fossils for my friend as an early Christmas present and I'm trying to figure out what they are. Most of them are brachiopods and clams but I'm having trouble identifying the genus of these guys. I have no information on where they came from or what period they're from. Can you guys help me as best as you can? IMG_3331.HEIC IMG_3332.HEIC

Hello everybody So this is a question not directly regarding fossils, but I feel this is nevertheless the right place. Is there any information on how big the teeth of modern great white sharks can get? For Megalodon there is a great amount of information regarding the size of the teeth. But for modern great whites I only find information about the size of the whole shark. I would like to make a small display with my 5.64 inch Meg tooth and a modern great white. I was able to get a 2.4 in modern white shark tooth. But I dont know if this is big or average.

In my last couple of collecting trips I have found some larger than normal vertebra from the Australian ichthyosaur platyptergius australis. What I am after is some literature that may enable me to calculate the length of an ichthyosaur based on the vertebra size. I realise that the approximate body position the vertebrae will need to be a major part of the calculation. Previously the larger vertebrae I found were around 80 mm diameter x 25 mm thick and quite often vertebrae from infants were also found with these so I had assumed fully grown. The last couple of vertebra ha

Hey everyone, I've been wondering why pyrite fossils are almost always small compared to others of the same species. does it have anything to do with the way the fossil is formed or is it something else entirely? thanks in advance!

Hello together. I just started to take a look at Desmostylia, as they still miss in my marine tetrapod collection (of more or less selfmade models) I read in several derivative descriptions that the biggest species (without a name being mentioned) where similar in size to stellers seacow, i.e. 7-9 meters. I believe that goes back to an article by Nicholas D. Pyenson and Geerat J. Vermeij where marine top feeders are compared by skull size. As Stellers seacow has an exceptionally small head for its size I wonder if that comparison makes sense? I´d appreciate any

I was wondering , if the thickness of fossil turtle shell is relative to the size of the turtle, is there a generic formula for estimating how large the turtle would be based on shell thickness of a fragment ?

Hi, I really want to know what the size of the mosasaur Liodon was. I can't find any info about it. I have also heard that it might was Prognathodon. Do someone know?
