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

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 encourage you to not do's not hard to remember!

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.
100% agree with you.
Also, it makes me so happy to see all the synonyms for T. rex listed in the artist's comments. :D

This makes me really happy :)
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.
