• Robert Bakker noted that it is likely that the stegosaur tail was much more flexible than those of other ornithischian dinosaurs because it lacked ossified tendons, thus lending credence to the idea of the thagomizer being a weapon.
• From 1995 onward at the Howe-Stephens Quarry in Big Horn County, Wyoming, named after the historic location of the Howe Ranch, once explored by Barnum Brown, and the new owner Press Stephens, Swiss palaeontologist Hans Jacob Siber excavated stegosaur specimens.
• Most named species, among them Astrodon pusillus from Portugal based on stegosaur fossils, she considered to be nomina dubia.
• In 2017, Peter Galton and Krishnan Ayyasami reaffirmed that Dravidosaurus was a stegosaur and announced that further likely stegosaurian fossils from the same original site were currently being studied.
• The approximate age of Wuerhosaurus is 130 mya, based on the approximate dating of the Tsaganstabian fauna, and thus the stegosaur would have lived in the Hauterivian era, which is roughly coeval with the Wealden group, from which other stegosaur material has been found.
• He presided over some of the most important fossil discoveries in history, such as those of the prosauropods Lufengosaurus and Yunnanosaurus, the ornithopod Tsintaosaurus, and the gigantic sauropod Mamenchisaurus, as well as China's first stegosaur, Chialingosaurus.
• Other animals from the Kirkwood Formation include the iguanodontian Iyuku, the stegosaur Paranthodon, the ornithomimosaur Nqwebasaurus, and several other unnamed dinosaurs.
• Other deposits from the Amoreira–Porto Novo Member at Porto Dinheiro have contained material from the sauropods Zby and Dinheirosaurus, the theropods Lourinhanosaurus, Torvosaurus and Ceratosaurus, ornithischian remains from the stegosaur Miragaia and an intermediate member of Iguanodontia, a possible pleurosternid turtle, and scales from the fish Lepidotes.
• Panoplosaurus was originally classified as a stegosaur related to the similarly armoured form Ankylosaurus, a group that was later divided with ankylosaurs becoming their own group.
• A 2018 redescription by Hao et al clarified aspects of the anatomy and found that it was an intermediate basal stegosaur, sharing basal traits with huayangosaurids as well as somewhat more advanced traits with other stegosaurs.
• An unnamed stegosaur and the pliosauroid plesiosaur Sinopliosaurus are also known from this formation but they were found an indeterminate member.
• A supposed dermal spine long thought to be from a stegosaur is actually a caudal vertebra referable to Archosauria indet.
• Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species Garbina roeorum have been reported from the formation since the 1990s.
• However, a 2017 phylogeny of stegosaurids by Thomas Raven and Susannah Maidment found that Alcovasaurus lacked the fusion between the trochanters of the femur seen in adult eurypodans (stegosaurians and ankylosaurians), which means that it cannot be confidently placed as a stegosaur.
• Lockley and Christian Andreas Meyer published more research on the possible Hettangian stegosaur footprints from France.
• Dinosaurs contemporaneous with Xiyunykus in the Tugulu Group of Xinjiang include the stegosaur Wuerhosaurus, the coeval alvarezsaur Tugulusaurus, the carcharodontosaurid Kelmayisaurus, the dubious maniraptoran Phaedrolosaurus, the problematic coelurosaur Xinjiangovenator, and the ceratopsian Psittacosaurus xinjiangensis.
• Her contributions have included overall revisions of the systematics of the group, the description of the Portuguese stegosaur Miragaia, the description of the oldest known stegosaur, Adratiklit, from the Middle Jurassic of Morocco, the oldest known ankylosaurian Spicomellus, also from Morocco, anatomical and systematic revisions of Chinese stegosaurs, and work on the postcranial skeleton and body mass of Stegosaurus.
• Minimocursor would have lived alongside several fish and turtles, an indeterminate pterosaur, an indeterminate stegosaur, an indeterminate metriacanthosaurid, an indeterminate mamenchisaurid, and the thalattosuchian Indosinosuchus.
