Hydropelta
Hydropelta is a genus of Late Jurassic turtle from marine deposits in the Jura Mountains of eastern France. Like many other eurysternid taxa, "Hydropelta" was at times considered the same species as "Eurysternum". Originally described as a species of "Chelone", it was renamed "Hydropelta" by Hermann von Meyer in 1860. Later, it was synonymized with "Eurysternum" by Oertel (1915), but was treated as a distinct genus and possibly a synonym of "Solnhofia" by Lapparent de Broin et al. (1996). However, "Hydropelta" is distinct from other eurysternids by the characters of the fontanelles and plastron.
