Here, morphological variation in Paleozoic atrypide morphology at the subfamily level (Atrypinae and Variatrypinae) from the Silurian and Devonian time intervals in the third Paleozoic EEU (~444-359 my) were investigated using relatively new techniques of quantitative modeling. The study explains how a group of closely related taxa in atrypide subfamilies exhibit morphological conservation through time in P3 EEU within the Eastern North America region.SpringerBriefs in earth sciences.PaleobiologyBrachiopodaPaleobiology.Brachiopoda.560Bose Rituparna1058870MiAaPQMiAaPQMiAaPQBOOK9910739433303321Palaeobiology of Middle Paleozoic Marine Brachiopods3553833UNINA
