TAPEWORM BODY FOSSIL

A team of international scientists has found a tapeworm body fossil in a mid-Cretaceous Kachin amber, dating back approximately 100 million years, according to the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences.

This fossil displays unique external and internal features that are most consistent with the tentacles of extant trypanorhynch tapeworms that parasitize marine elasmobranchs (mainly sharks and rays).

Cestoda, or tapeworms, are a specialized endoparasitic group of flatworms. They have a complex lifecycle requiring at least two different hosts, and are known to infect all major groups of vertebrates. Due to their soft tissue and concealed habitats, their fossil records are extremely sparse.
