The team at Gage Beasley Prehistoric is constantly engaged in researching and discovering interesting information about extinct animals.
In doing so, we often find ourselves captivated by the mesmerizing names attributed to these extraordinary creatures.
Whether it’s their given name or the meaning behind it, there’s no denying the sheer awesomeness that some of these names possess.
With this in mind, we pondered upon the idea of compiling a list of our favorite names and arranging them in a captivating countdown from 20 to 1.
And here we are!


Why We Made The List
Initially, our team built a list of 100 species that were considered to be the best candidates.
This was based on what they found to be some of the meanest, funniest, or most creative names.
As we mentioned earlier, this is based on either their given name or the name’s meaning.

We looked for names that stood out from the crowd, were unique to the species, and showed a bit of personality.
We then further narrowed our list down to 20 species that best represented what we thought were the greatest names of all.
We hope you enjoy it. Surely, you will encounter some species you’ve never heard of before.
Let us know your favorite in the comments below!
Who will take the crown?
