Hi all, A bit of a newbie so apologies if this is a dumb question but was hoping for the naming nomenclature a bit more. I understand that sp. means species (used when the species is unknow, but the genus isn't) and indet. means indetermined. But what does cf. mean? classification? I've seen it used before the genus and also after followed by a person's name. For example, I read on this forum a tooth found in the Bull creek canyon formation belonging to cf Coelophysis. Aswell as ready of a Apachesaurus cf. A gregorii. Are there any other terms that are frequently used?

Confusion about cf. and indet. in labeling of specimens
-Andy- posted a topic in Questions & Answers
Hi all, in what situation would we use the following naming conventions? 1) Tyrannosaurid sp. 2) Tyrannosaurid indet. sp. OR Tyrannosaurid indet. (which is correct?) 3) cf. Tyrannosaurid sp. -
What is the definition of a “described” species?
Sagebrush Steve posted a topic in Questions & Answers
What does it take for a species to officially be “described”? I know there must be more than just having a paper written about it, there must be some minimum requirements for the contents of the paper. And am I correct that you can’t establish a full species name unless it has been “described”? -
As I understand, there are several practices when naming fossils. If I have a confirmed mosasaur tooth in which I know the definite species, I name it: Tylosaurus proriger If I have a mosasaur tooth in which I know the genus, and the species resembles T. proriger, but I am slightly unsure, I name it: Tylosaurus cf. proriger If I have a mosasaur tooth which looks just like T. proriger, but I know it's a different species for sure, I name it: Tylosaurus aff. proriger If I have a mosasaur tooth in which I know the genus but not the species, I label it: Tylosaurus sp. OR Tylosaurus indet. If I have a mosasaur tooth in which I cannot identify the genus, but it resembles the Tylosaurus family, I name it: cf. Tylosaurus sp. Did I get that correct? .sp = 'species' .cf = 'confer' meaning 'compare with' .aff = 'affinis' meaning 'it has affinities of that species' .indet = 'indeterminate' meaning 'there's no way to confirm this' Next up, what if I have a mosasaur tooth that is worn down, but comes from an area with high Tylosaurus density. I know it's probably Tylosaurus, but I can't be sure. Is there any way of labeling a fossil with the message: This is probably a Tylosaurus?

Hi all, I like to put proper labels on all my fossils, and I usually do it like this Example: Petrified Wood Conifer araucaria 195 mya Madagascar However, I 've occasionally seen labels on other fossils that go by Fossilized Tooth Mosasaur sp. 144 - 65 mya Morocco My question is with the "Mosasaur sp." part. I understand a standard labeling convention usually includes the scientific name of the species involved. However, what does Mosasaur sp. mean in this case? Is it referring to the fact that the tooth in question belongs to a mosasaur, but is not narrowed down to any one particular species. Also, when I look at the naming of the Tyrannosaurus, it can go like this. Dinosaur Tooth T. rex 67 mya North America Why would the mosasaur naming go for "sp." while the Tyrannosaurus naming go for "T."
