The Xi-sub-b is categorized as a baryon, which are formed of three quarks. Commonly known baryons include the proton as well as the neutron."

Nope. They made them.
It's possible, even likely, that something somewhere else (supernova, the big bang, etc.) made some in olden times. But these were brand-spankin' new.
