通常，美国亚利桑那州石化森林国家公园上三叠统钦勒组中的化石木材不会出现年轮生长，但含有不规则的生长中断，类似于现在生长在潮湿热带的树木。这些中断可能是由于内源性激素影响或偶尔出现的供水局部变化造成的。因此，可以得出结论，该公园的晚三叠世化石森林生活在允许树木持续生长的条件下。来自公园以外地区的有限数据表明，在晚三叠世，美国西南部邻近地区也出现了类似的情况。尽管据报道，该地区在晚三叠世受到季风环流模式的影响，但树木的生长似乎没有受到太大影响。
Typically, the fossil woods in the Upper Triassic Chinle Formation in Petrified Forest National Park, Arizona, USA do not show annual growth rings but contain irregular growth interruptions similar to those found in trees now growing in the humid tropics. These interruptions could be due to endogenous hormonal effects or to occasional local variations in water supply. Therefore, it is concluded that the Late Triassic fossil forests in the park lived in conditions that permitted continuous tree growth. Limited data from areas outside of the park suggests that similar conditions prevailed in adjacent areas in the southwestern United States during the Late Triassic. Although this region is reported to have been under the influence of a monsoonal circulation pattern during the Late Triassic, the growth of the trees does not appear to have been greatly affected.
