I'd like to highlight a niche paper by Hans Pellmann (2021) that documents branchiopod crustacean aktuo-paläontologie--documenting what happens in the modern world BEFORE fossilization. First, a dried out community of the clam shrimp Limnadia lenticularis (photo b J. Venzlaff). #arthropoda #crustacea #branchiopoda #spinicaudata #conchostraca #taphonomy #fossilization

A new paper by Poschmann & Schindler 2023 describes specimens of the fossil clam shrimp, Palaeolimnadiopsis obenaueri (Guthörl, 1931) with the impressions of eggs. #arthropoda #crustacea #branchiopoda #paleontology #Palaeontology #fossil #Permian #Germany #spinicaudata

This seems like an easy case for uniformitarianism. Modern clam shrimp live in ephemeral freshwater bodies, ergo fossil clam shrimp indicate ephemeral bodies of freshwater. Simple! #branchiopoda #paleoecology #paleontology #palaeontology #spinicaudata
