In Depth Microraptor was first presented to the world as part of the composite fossil called Archaeoraptor, where the tail of a Microraptor was added to the upper body of a Yanornis. Archaeoraptor was a scandalous fake that made headlines around the world, but in the aftermath of this, Microraptor would become known to science. … Read more
In Depth The dromaeosaurids are a very popular group of dinosaurs that all share a few common features. These include reasonably lightweight build, long stiff tails for balance, legs and pelvis adapted for very fast running and a large sickle shaped claw on the second toe of each foot. Balaur however is a dromaeosaur with … Read more
In Depth Changyuraptor is another of an increasing number of dromaeosaurid dinosaurs that have been dubbed ‘four-winged dromaeosaurs’. This is because Changyuraptor did not just have well developed pennaceous feathers on the arms; they also grew from the back of the legs. The first of these dromaeosaurs to be described was Microraptor which is speculated … Read more
In Depth Named after the title character in the 1942 film Bambi, Bambiraptor was a small dromaeosaurid dinosaur that has caused a lot of excitement in the science of palaeontology. Discovered by a fourteen year-old Wes Linster in 1993, the Bambiraptor holotype is of an exceptionally well preserved individual that is estimated to be around … Read more
In Depth When Shanag was first described the genus was described as a member of the Dromaeosauridae, but later studies have refined this further to suggest that Shanag was closer to dromaeosaurid genera such as Microraptor. So far Shanag is only known from partial jaw material, but analysis and comparisons to other related genera suggests … Read more
In Depth Wulong is a genus of microraptorine dromaeosaurid dinosaur that lived in China during the early Cretaceous. The holotype individual of Wulong is of a juvenile, so a full adult size for this dinosaur is unknown at the time of writing. Other microraptorine dinosaurs however are usually smaller than other dromaeosaurid dinosaurs, and like … Read more
In Depth Originally thought to be a juvenile of a species of Megalosaurus, Nuthetes was later established as a distinct genus. Today Nuthetes is thought to represent a possible dromaeosaurid dinosaur, but the key word here is ‘possible’. So far Nuthetes is only known from teeth and a fragment of jawbone, making such things as … Read more
In Depth Boreonykus is a genus of dromaeosaurid dinosaur that lived in Canada during the late Cretaceous. Further Reading - A high-latitude dromaeosaurid, Boreonykus certekorum, gen. et sp. nov. (Theropoda), from the upper Campanian Wapiti Formation, west-central Alberta. - Journal of Vertebrate Paleontology e1034359. - P. R. Bell & P. J. Currie - 2015.
In Depth Atrociraptor has been described from very incomplete remains, but two clear observations can be made about this dinosaur. One is that the snout appears to be both deeper and shorter than most other dromaeosaurs, something that could indicate a strong bite due to larger muscles and the outer teeth being placed closer to … Read more
In Depth Although not very well known, Tianyuraptor is important to many palaeontologists because it is often regarded as a transitional form that links northern and southern genera of dromaeosaurids. Tianyuraptor is noted for having a smaller than usual furcula and arms that are proportionately much smaller than those of other dromaeosaurid genera. Overall, Tianyuraptor … Read more
