Thecideida
| Description | Thecideida is an order of cryptic articulate brachiopods characterized by their small size and habit of cementing their ventral valves to hard substrates such as shells, rocks and carbonate hardgrounds. Thecideides first appear in the Triassic (Jaecks and Carlson, 2001) and are common today (Lüter, 2005; Lüter et al., 2007).
