''Chronoperates'' (meaning "time wanderer" in Greek) is an extinct genus of probable mammal whose remains have been found in a late Paleocene deposit in Alberta, Canada. It is represented by the type species ''Chronoperates paradoxus'' and known only from a partial left lower jaw. It was first identified in 1992 as a non-mammalian cynodont, implying a ghost lineage of over 100 million years since the previously youngest known record of non-mammalian cynodonts, which at that time was in the Jurassic period (some non-mammalian cynodonts are now known to have persisted until the Early Cretaceous). More recently, ''Chronoperates'' has been interpreted as a late-surviving symmetrodont mammal. ==References==
