This study describes four new fossil tick species found in Burmese amber, including the oldest record of Ixodidae ticks, which may have a relationship with modern Australian species. The discovery of a transitional tick species, Khimairidae, combining characteristics of soft ticks and hard ticks is particularly remarkable. The study also introduces a new species of extinct Deinocrotonidae and associates a female individual of Cornupalpatum burmanicum with a dinosaur feather barb.
Four fossil ticks (Arachnida: Parasitiformes: Ixodida) are described from mid-Cretaceous (ca. 100 Ma) Burmese amber of Myanmar. Ixodes antiquorum sp. nov. (Ixodidae) is the first Mesozoic record of Ixodes and the oldest representative of the most species-rich extant tick genus. Its affinities appear to lie with modern Australian forms, consistent with the hypothesis that Burmese amber hosted Gondwanan faunal elements. Even more remarkable is Khimaira fossus gen. et sp. nov. which combines a body resembling that of a soft tick (Argasidae) with a basis capitulum more like that of a hard tick (Ixodidae). We refer it to Khimairidae fam. nov. as a possible transitional form between the two main families of ticks alive today. Another member of the extinct Deinocrotonidae is described as Deinocroton copia sp. nov., while the first described adult female for Cornupalpatum burmanicum is associated with a dinosaur feather barb.
