• Unexpected chaotic features are found in time series of successive air shower (E>3×10^<14>eV) arrival time intervals. Over 99.9 % of air shower arrival time intervals obey the Poisson distribution law representing stochastic behaviors, but there are occasionally air showers showing real chaotic behaviors as distinguished from both random and colored noises. With two systems of the Kinki university installations, we found 11 cases showing chaotic time series in about 5 years in both the systems (3.4 years with system-1 and 1.4 years with system-2). In a remarkable example of September 19, 1991, the correlation dimension was observed to have dropped from about 4 to about 2 and recovered smoothly in 2 days in nearly the same period of time in three observing stations separated from each other by several 100kms. A formation of chaos structure due to energetic cosmic ray dust particles is suggested. Progress of new cosmic ray physics phenomena may be expected with the study of air showers marked with chaos.
