This note reports the first findings of fossil relicts in the sedimentary record of the Itajai Basin (Santa Catarina State - Fig. 1). The fossil remains, which belong to Chancelloria sp., were recently presented to the 15 th Brazilian Paleontological Congress (Leipnitz et al. 1997) and support both a marine depositional environment and a Cambrian age of the uppermost unit of the Itajai Group (Campo Alegre Formation). The conclusions about a Cambrian age and a marine environment are also supported by trace fossils recently described in the same succession (Netto & Zucatti da Rosa 1997).
