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

How can we understand the evolution of the group with so few characters? Do we just pass over it in silence? 4/4

The interesting thing is highlighted by the title. Despite the 'marine' nature of the deposit, clam shrimp are ephemeral freshwater specialists today.
