Khimaira is an extinct genus of Cretaceous tick found in Burmese amber from Myanmar, and the only member of the family Khimairidae. The genus only has one species, Khimaira fossus.[1] The genus was named after the chimera, a creature in Greek mythology.[2] The species, which is known from a juvenile (nymph) specimen, combines a soft body similar to those of argasid ticks with mouthparts more similar to those of hard-bodied ixodid ticks.[1] The discovery of Khimaira fossus represents a possible missing link between soft and hard bodied ticks.[3][1]
