In August 1963, living conchostracans (branchipod Crustacea) of the genera Leptestheria and Eulimnadia were collected at three stations in Chihuahua. One Sonoran locality yielded Triassic fossils of the family Cyzicidae, a widespread North American group. The geographic rangeof the geologically younger families Leptestheriidae and Limnadidae (particularly the genus Eulimnadia) thus extended to Chihuahua during post-Mesozoic time.
1963 年 8 月，在奇瓦瓦的三个地点采集到生活的介形纲动物（鳃足纲甲壳动物）属 Leptestheria 和 Eulimnadia。一个索诺拉地方的产地产有 Cyzicidae 科的三叠纪化石，这是一个广泛分布于北美的群体。因此，在新生代后期，地质上较年轻的 Leptestheriidae 和 Limnadidae 科（特别是 Eulimnadia 属）的地理范围扩大到了奇瓦瓦。
