Therizinosauria is a group of unusual theropod dinosaurs known from Cretaceous deposits in Asia and North America. The clade exhibits unique features, including lanceolate teeth, a rostral rhamphotheca, and a broad, opisthopubic pelvis. Some of those characteristics are associated with a shift in dietary preferences and an adaptation to herbivory. But the most striking feature, as exemplified by the large-bodied Therizinosaurus from the Late Cretaceous of Mongolia, is the presence of tridactyl (three-fingered) hands with three large claw-like unguals.

The annual EGU General Assembly is a wonderful chance to gather together with friends and colleagues to discuss recent scientific work, plan new projects and develop your career, but a scientific meeting, especially one the size and length of time of the General Assembly is not an equally accessible experience for everyone. With this in mind over the years EGU have developed a range of resources aimed at increasing the accessibility of the meeting to a more diverse group of people, but if you are unsure what those resources are, we have gathered many of them in this blog to help you find them, whether you are a person attending with children, with a disability, with specific religious requirements, travel challenges or any other reason, to help you have the best meeting possible!
