Supplemental Material: Body-size reductions in dacryoconarid tentaculitoids during Late Devonian warming

Figure S1: Log-transformed adult volume distributions for each sampled interval. Figure S2: Log-transformed initial chamber volume distributions for each sampled bed. Figure S3: Evolutionary trajectory modeling. Figure S4: Family-level stratigraphic trends in mean log-transformed initial chamber volumes (A), adult volumes (B), and adult to initial chamber ratio (C). Figure S5: Geochemical proxy data for nutrient availability (A–C) and redox conditions (D–E) relevant interval spanning the upper West River Formation through the punctata zonation of the lower Rhinestreet Formation from Akzo core 9455.
