The authenticity of an artifact created by this culture was called into question by the presence of a so-called “cootie glyph.” Thor Heyerdahl cited the presence (-5[1])of a figure known as “Uncle Sam” (10[3])in this culture’s art as evidence that (10[1])it had Nordic ancestry. (10[1]-5[2])A successor to this culture wrote in the Isthmian script. (-5[1])This culture’s (10[1])art was the product of contact with Africa according to Ivan Van Sertima. (10[1]-5[2])This culture (10[1])created (10[1])“elongated (10[1])man” figurines (-5[1])as well as a greenstone (10[1]-5[1])statue (-5[1])of a man holding a were-jaguar. (10[5])This culture (10[3]-5[1])was the (10[1])first (10[1])to mix (10[2]-5[1])latex (10[2]-5[1])with morning-glory juice (10[3])to create (10[1])the rubber balls (10[1])used in a ceremonial (10[5]-5[1])game. (10[3]-5[9])Each (0[1]-5[1])of the ten (-5[2])monumental basalt (-5[2])sculptures (10[1])left by this (10[1])culture at San Lorenzo (10[2])has (10[3])a unique helmet. (10[3])For 10 points, name this Mesoamerican culture that built colossal stone (10[1])heads. (10[2])■END■ (10[16])
