在澳大利亚吉普斯兰南部的Koonstella下白垩统粉砂岩中，采集到两种跳蚤，以及丰富的鱼类、植物、叶足类甲壳动物（叶甲纲、无甲纲和枝角类）和其他昆虫的遗骸。昆虫区系主要包括蜉蝣目（蜉蝣）、双翅目（蠓）、鞘翅目（甲虫）、鳞翅目（石蝇）和蜻蜓目（蜻蜓和豆娘）的水生未成熟阶段。此外，还保存了蝎蛉科（长翅目）的水生幼虫。还有一小部分成年昆虫的外来动物群，包括跳蚤，其未成熟阶段不是水生的。唯一已知的温血脊椎动物遗骸是羽毛。
Two fleas have been collected in association with abundant remains of fish, plants, phyllopod Crustacea (Conchostraca, Anostraca and Cladocera) and other insects in a Lower Cretaceous siltstone at Koonwarra, southern Gippsland, Australia. The insect fauna consists mainly of the aquatic immature stages of Ephemeroptera (mayflies), Diptera (midges), Coleoptera (beetles), Plecoptera (stoneflies) and Odonata (dragonflies and damselflies). The aquatic larvae of the scorpionfly family Nannochoristidae (Mecoptera) are also preserved. There is also a small adventitious fauna of adult insects, including the fleas, the immature stages of which are not aquatic. The only known remains of warm-blooded vertebrates are feathers1.
