Evidence of vector-borne disease in dinosaurs?

Abstract: "A blood-filled sand fly, _Palaeomyia burmitis_, was recently described from Early Cretaceous Burmese amber. Within the alimentary canal of this sand fly were the amastigotes and promastigotes of a digenetic leishmanial trypanosomatid. Inside the lumen of the thoracic midgut of the fossil sand fly were nucleated blood cells, some of which were intact and others in various stages of lysis and disintegration. The present study identifies these blood cells as reptilian and describes putative developing amastigotes inside spherical to oval whitish vacuoles within some of the fossil blood cells. The significance of this find is discussed, especially regarding the high possibility that Cretaceous dinosaurs were infected by trypanosomatids."

In the Appendix of this paper is a brief description of how dinosaur DNA was extracted from the blood cells, and used to clone a living sauropod dinosaur. The sauropod was kept in a pen behind the research lab.

Just kidding.  (The paper is real though.)
