Early ceramic-producing tradition of incipient horticulturalists on the Ucayali River near Pucallpa in the Peruvian Amazon, identified by Donald Lathrap in 1970 near Yarinacocha lagoon and split into an Early phase (c. 2000-1800 BCE) — among the oldest pottery yet found in Peru — and a Late phase (c. 1600-1400 BCE).
Lathrap argued Tutishcainyo Temprano influenced the Wayra-jirca ceramic phase at Kotosh in the adjacent highlands (c. 1800 BCE) and ceramics at the Las Lechuzas cave near Tingo María (c. 1600 BCE); the tradition itself was succeeded by later Ucayali basin ceramic traditions (e.g. Cumancaya, much later).
By the excavator of Tutishcainyo; foundational statement of the site's ceramic sequence and its role in Lathrap's 'Amazon as source' hypothesis for Andean pottery.
Places the Tutishcainyo sequence within the broader continental picture of earliest Formative ceramics.
