Never thought to check, didn't even consider that. edit: checked and it's not 'This item cannot be dragged to here' so I guess it's another stackable.
Check the item info. It just says Animal Part, like halix leg fur. It would say DNA if it were to be used in DNA.
If it's used in DNA, no need to have the word DNA in description, even tho we are spoiled with useful info at Ark if don't have to say DNA. Does it go into a refiner it's most likely a DNA part, and A-team said DNA would start to drop soon too. Now just figure out what other stuff it probably would need. Edit: so guess this isn't a DNA part, or they remade the whole system..
The DNA recipes are given in the info window, though you probably already noticed that now that a couple DNA pieces have dropped.
