The Callide Basin Lower Jurassic units had been noted two decades ago as having preserved dinosaur ichnites, however, none had been shown or described at that time. The current study is the first to describe a dinosaur track from this region, a fossil collected over a decade ago from an overburden dump from the Callide Mine (Dunn Creek mine area). The track morphologically resembles those of a large Anomoepus-like 'Anomoepid' and confirms previously unsubstantiated reports of ornithischian tracks at the location. The tracksite represents the third Early Jurassic dinosaur fossil site in Australia. All of these are tracksites restricted to Central Queensland with the Biloela track the only known Australian Jurassic dinosaur print preserved as a concave epirelief (impression). The find contrasts with earlier statements that the open-pit mining practices make the discovery of dinosaur tracks unlikely. Instead, the extraction of overburden rock has the potential of re-discovering additional fossil track-bearing strata. It is hoped that there will be further discoveries made within the region.

We re-evaluate fragmentary eggshells of avian affinities (ratite morphotype) from the Late Cretaceous Intertrappean beds of Anjar (District Kachchh, Gujarat), India in view of additional material and cladistic analysis. Previously, Anjar eggshells were encompassed in the oofamily Subtiliolithidae; however, now the oofamily Subtiliolithidae has been re-examined as a junior synonym of the oofamily Laevisoolithidae. External surface of the eggshells is smooth to rugose, with unevenly distributed, sub-rounded tubercles; average eggshell thickness (467â491 Âm) characterised by two layers: (1) a well-differentiated mammillary layer (196.1 Âm), comprising conical, crystalline aggregates with petaloid wedges, and (2) a continuous spongy layer (274.58 Âm, CL:ML, 1.3:1) divulges a squamatic zone. The eggshells have been compared with three oofamilies (Elongatoolithidae, Prismatoolithidae and Laevisoolithidae) and their palaeoecological implications have been discussed in detail. Shell microstructure is comparable with oofamily Laevisoolithidae, an ootaxon usually related with enantiornithid birds. Cladistic analysis performed on the eggshells are consistent with the avian kinships recognised based on macro, micro and ultrastructural features.
