A new hadrosauriform dinosaur, Jintasaurus meniscus gen. et sp. nov., is reported from the Lower Cretaceous Xinminpu Group of the Yujingzi Basin, Jiuquan area, Gansu Province, northwestern China. It is represented by an articulated posterior portion of the skull and is unique in having an extremely long, pendant and crescentic paroccipital process with its ventral tip projecting far beyond the ventral level of the occipital condyle. Phylogenetic analysis recovers Jintasaurus as the sister-taxon to Hadrosauroidea, more derived than other Early Cretaceous hadrosauriforms and Protohadros from the early Late Cretaceous of North America. This discovery adds one more close relative to Hadrosauroidea in Asia and supports an Asian origin for this group.

A new specimen of a therizinosauroid dinosaur recovered from the Lower Cretaceous Xinminpu Group in the Yujingzi Basin of the Jiuquan area, Gansu Province, northwestern China, consists of a partial postcranial skeleton, including a well-preserved left half of the pelvic girdle. It is referred to Suzhousaurus megatherioides Li et al., 2007 based on the autapomorphic anterior concavity of its pubic shaft and is the second known specimen of this taxon. Comparisons of the structure of therizinosauroid pelvic girdles show that the pelvis of Suzhousaurus possesses several unique features, including a laterally deflected, thin, and flat preacetabular process of the ilium, a smoothly curved anterodorsal margin of the preacetabular process of the ilium, and a concave anterior margin of the pubic shaft. Cladistic analysis confirms that Suzhousaurus is more derived than the Early Cretaceous therizinosauroids Falcarius and Beipiaosaurus , less derived than Late Cretaceous forms, and likely closely related to Alxasaurus from the Early Cretaceous of Inner Mongolia, China.

Species Being

Stratiomyomorpha (soldier flies and allies) is an ingroup of Diptera, with a fossil record stretching back to the Early Cretaceous (the Barremian, about 125 MYA). Stratiomyomorpha includes at least 3,000 species in the modern fauna, with many species being crucial for ecosystem functions, especially as saprophages. Larvae of many stratiomyomorphans are especially important as scavengers and saproxyls in modern ecosystems. Yet, fossil larvae of the group are extremely scarce. Here we present 23 new records of fossil stratiomyomorphan larvae, representing six discrete morphotypes. Specimens originate from Cretaceous amber from Myanmar, Eocene Baltic amber, Miocene Dominican amber, and compression fossils from the Eocene of Messel (Germany) and the Miocene of Slovenia. We discuss the implications of these new records for our understanding of stratiomyomorphan ecomorphology in deep time as well as their palaeoecology.
