"A small, eroded head of a feline (jaguar) sculpted in the round, about 1.25 m (4 feet) long and .7 M (2 1/2 feet) high. Four columns of hieroglyphs are carved on the back of the head. A historical date, counted from the period ending 4 Ahau 13 Yax (126.96.36.199.0), is given in the first three rows of glyphs in the two columns on the left, recorded as 1120 days (2 uinals plus 3 tuns) later to reach 6 Ahau 18 Zac. The date corresponds to the early years of Cauac Sky's reign and, although not referred to here by his later name glyph, several titles used in his later texts appear in the right-hand column. The last glyph in the text represents the earliest known use of the Quirigua "Emblem Glyph" at the site."
