What company makes a good one? Not Hyenadon just a plain Hyena. Hyenadon goes to AAA. Great figure. Btw.
Yes, we know the difference between creodonts and carnivorans. The best Hyaenodon is from Mojo, not AAA.
As for modern hyaenas, I am partial to the Mojo and Safari spotteds, and the CollectA Striped.
Worst currently available one? Papo. It looks like a racist cartoon.
