Abstract
 

Highlights

  • Mid-Cretaceous lizard.
  • Trematode metacercaria.
  • Myanmar amber.
  • X-ray microcomputed tomography.

 

X-ray microcomputed tomography was used to reveal putative trematode metacercariae (Platyhelminthes: Digenea) located in cysts positioned at the base of the femora in a 100 myr agamid lizard preserved in Myanmar amber. The cysts are characterized and compared with encysted metacercariae recovered from a similar location in an extant Anolis lizard. This discovery provides evidence that lizards were serving as intermediate hosts of trematodes some 100 Ma.
