More research is needed to find out what their host was at that time, although current understanding suggests it's unlikely they fed on the blood of dinosaurs. This is because bed bugs and all their relatives feed on animals that have a "home—such as a bird's nest, an owl's burrow, a bat's roost or a human's bed—a mode of life that dinosaurs don't seem to have adopted.
An international team of paleontologists has announced the discovery of an ancient interaction preserved in a 16-million-year-old (Miocene period) piece of amber from the Dominican Republic: a winged termite and an ant along with 25 springtails (one of the oldest terrestrial arthropod lineages living today) attached or in close proximity to the wings and legs of their hosts. This discovery highlights the existence of a new type of hitchhiking behavior among wingless terrestrial arthropods, and could be key to explaining how symphypleonan springtails successfully achieved dispersal worldwide.
