Das bekommt ihr sehr oft beim töten eines Argentavis.
This and some other drops are made to start boss fights
Each argentavis drops 2 claws hence they have two legs.they are also used in spawning some bosses.
Kill an Argie to receive these claws.
Just make litle chest and put them in there so you can have litle trophey collection
(You can also put sarco skin,t rex's head,megalodon teeth and etc...)
