The Fossil Record

26.7K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Summary

Fossilized parasite eggs found in Early Cretaceous coprolites from Spain reveal ancient fish and crocodylomorph hosts. This discovery sheds light on early host-parasite relationships in a lacustrine ecosystem.

Area of Science:

  • Paleontology
  • Parasitology
  • Paleoecology

Background:

  • The Las Hoyas fossil site in Spain is rich in vertebrate coprolites, complicating parasite identification.
  • Previous studies have identified various coprolite morphotypes, but parasite content remains largely unexplored.

Purpose of the Study:

  • To investigate the parasitic content of coprolites from the Las Hoyas fossil site.
  • To identify specific parasite eggs and their potential hosts within the Early Cretaceous ecosystem.

Main Methods:

  • Analysis of 29 coprolites previously classified into distinct morphotypes.
  • Microscopic examination of coprolite contents for parasitic eggs.

Main Results:

  • Parasitic eggs, including digenean trematode and nematode (ascaridid) eggs, were identified in two coprolites.
  • This represents the second record of such eggs from an Early Cretaceous locality.
  • Cylindrical coprolites likely indicate crocodylomorph hosts for anisakid eggs, while bump-headed lace coprolites suggest fish as hosts for trematodes and ascaridids.

Conclusions:

  • The Las Hoyas fossil site (126-129 Ma) provides evidence of early host-parasite associations.
  • A connection between basal Gonorynchiformes fish and digenetic trematodes is documented.
  • Crocodylomorphs and fish played roles as hosts or intermediate hosts for ancient parasites.
