Target 1 Dinosaur-Type monster you control; equip this card to that target. It gains 1000 ATK. When it destroys an opponent's monster by battle and sends it to the Graveyard: The equipped monster can make a second attack on an opponent's monster in a row.
Jurrac Spinos can special summon a token with 300 attack in attack position to your opponent's field when he destroys a monster your opponent controls. Survival of the Fittest will then give Jurrac Spino an extra attack which you can use to attack the token. With two Survival of the Fittests attached to Jurrac Spino, you can OTK your opponent when attacking the token.

Is this card bugged? I destroyed monsters while it was equipped and the effect never went off.
Unfortunately, this website is wrong. Attaching a survival of the Fittest to a Jurrac Spinos does not give you the desired outcome (something I have experienced first hand). Had to read more carefully. It says ''When it destroys an opponent's monster by battle and sends it to the Graveyard: The equipped monster can make a second attack on an opponent's monster in a row.'' The key word here is opponent's MONSTER. A token is not a monster. So yes, I destroyed a monster and send it to the graveyard, summoning a Spinos Token onto opponent's field but I could not use survival of the fittest to attack that token. Sad really, I was so excited for the combo. Also remember that if you use Jurrac Spinos the next turn to destroy the token, again you are not allowed to use Survival of the Fittest (since you didn't destroyed a monster).
A token is a monster. I think you don't get an effect because the monster wasn't sent to the grave. Same thing with Masked Hero Anki destroying a summoned Paleozoic or a vampire retainer that was summoned with it's own effect.
