Abstract. Measurements of the lifetimes of the Lambda(c) decaying into p K pi and of the D(s) decaying into phi pi are presented. The data were accumulated in the Fermilab Wide-Band photoproduction experiment E-687. The lifetimes of the Lambda(c) and the D(s) are measured to be 0.20 +- 0.03 +- 0.03 ps and 0.50 +- 0.06 +- 0.03 ps respectively.
