Phytnatoderma is a complex, branching biogenic structure that is seldom mentioned in the ichnologic literature, although it may have been misidentified recently as “Zonarites” and large pellet‐filled “Chondrites”. The ichnogenus is usually interpreted as the product of subsurface deposit‐feeding animals. Well‐preserved examples from Pliocene slope mudstone in Ecuador are assignable to P. granulatum (Schlotheim, 1822). These structures are typically 30–40 cm in overall diameter; consist of outward‐branching, horizontal to subhorizontal, overlapping tunnels grouped in bundles; and have tunnel fills consisting of pelleted volcanic ash. The Ecuadorian Phymatoderma occur with a moderately rich ichnoassemblage that includes Alcyonidiopsis ichnosp., Chondrites intricatus, several kinds of Phycodes‐like structures, Phycosiphon incertum, Planolites ichnosp., Rorschachichnus amoeba, Scolicia ichnosp., Taenidium barretti, and Zoophycos ichnosp. Benthic foraminiferids and geologic context point to deposition on the u...
