Nomenclature for Beginners by ChrisMasna Nomenclature for Beginners by ChrisMasna

How to write and abbreviate a "scientific name", under the Linnaean system, and according to the International Code of Zoological Nomenclature.



The species is Tyrannosaurus rex, where rex is the specific epitetus. Here is called species because it gives the species, but it does not designate a species itself (it is never written just rex whithout the genus).

*Complete species should include author and year, though.

Example extracted from "The Complete Dinosaur, Second Edition".



Additional info (avalaible in Wikipedia):

T. rex may also refer to:

Tachyoryctes rex, the king mole rat, a rodent species
Tetragonodon rex, a seed shrimp species native to the Mozambique Channel
Thoristella rex, a sea snail species endemic to New Zealand
Trialeurodes rex, a whitefly species
Tyrannasorus rex, a fossil beetle species from the Miocene
Tyrannobdella rex, a leech species
Tyrannoberingius rex, a fossil gastropod from Miocene Alaska

Hello! I love your work. Thanks for posting this type of information. 

That said, I have a minor correction to this work. Technically, the "complete" species name includes the author who described it and the year it was published. In the case of T. rex, that would look like this: Tyrannosaurus rex Osborn, 1905. Obviously, most of the time species names are written without the authorship, but nevertheless leaving the authorship off is still "incomplete". Hope that is helpful!

Thank you for this!  Although I've read a lot of dinosaur books this fact really didn't sink
in.  Nice to know how to do it correctly.  You very rarely see that unless it's a scientific text book.  Too bad.

I agree, there's a lack of intermediate-level dinosaur books!

Well, because it's so ingrained in my head to right it hat way, I will continue to write it T-rex, no matter what anyone says!!

I think Kopout raised a fair point that T-Rex could possibly be considered the common name by now, but still, thank you for making this! Most people I run into don't know that T. rex is the proper way of writing it and get confused when I try to explain it to them. Hopefully this makes its way around DA and educates at least a few viewers.

I REALLY bothers me seeing people capitalizing both genus & species names. I also cringe when people pretend to build fake scientific names for their fictional creatures, which really isn't a bad thing except when they don't follow the rules for nomenclature & think they just have to string a bunch of Latin- or Greek-sounding words together.

I'd argue that T-Rex is a common name. This tends to happen with extinct animals, we have no ready common name so when they get popular one is made for them from the binomial name. Usually its just the species name but in this case its the abbreviation.

umm didn't think of that, to be honest. In spanish the common name is "tiranosaurio", so i guess "T-Rex" could be valid at the same level, as a common name. Yet, I consider necessary to know the correct/binominal form.

This gets to me so much! Thank you! I see you didn't include the all too common "TRex" which just makes me want to cry.

Sort of thing I know deep down already yet always write the wrong way - especially for "T. rex" (probably the first time I've ever written it correctly!)

The scientific name of the domestic dog is Canis lupus familiaris, not Canis familiaris ;)

Extracted literally from "The Complete Dinosaur". According with Holtz, there is a debate about whether to use the trivial nomen of the wild ancestor for domesticates or not.

I was going to point out that trinomial thing myself but I had no idea there was even a debate about it. Very interesting.

I still abbreviate it as "T-rex" for the simple reason it looks weird to me when there is the word T. rex in the sentence and the full stop between genus and species makes it look like there are two sentences. :P

And I´m too lazy to put italics into each of my comments/replys, particularly on DeviantArt where you have to enter some code for italics.

Aren't you familar with T. wrecks-rulez OSBORN, 1906?
One year after he described T. rex he thought that name would probably be never become a famous name. So he decided to give the animal the new name T. wrecks-rulez, after his german brother-in-law Dieter Wreck and his italian cousin Alfredo Rulezi.
Yes, I'm serious. :D
