Nature, 1970
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 ...

Science, 1978
Exceptionally well preserved larval bivalve shells have been isolated from Late Cretaceous (Maestrichtian) sediments. Specimens were readily identified to familial level on the basis of gross morphology and hinge structures. Reconstruction of fossil larval ontogeny, linked with the distribution of adult stages, will provide an important interpretative ...
