       Latenivenatrix has a somewhat convoluted history of discovery.‭ ‬The holotype specimen of the genus‭ (‬CMN‭ ‬12340‭) ‬was originally designated as being a Stenonychosaurus by Dale A.‭ ‬Russel in‭ ‬1969.‭ ‬Then in‭ ‬1987‭ ‬it was moved into the Troodon genus,‭ ‬the type genus of the troodontid dinosaurs.‭ ‬It was not until much later in‭ ‬2017‭ ‬that the specimen was used to establish a distinct new genus.
       Latenivenatrix was big for a troodontid dinosaur,‭ ‬and with an estimated size ranging between three and three and a half meters,‭ ‬Latenivenatrix is one of if not the largest troodontid dinosaurs known.‭ ‬Although not the biggest predator in the habitat,‭ ‬Latenivenatrix would have been a serious threat most similarly sized dinosaurs,‭ ‬including juveniles of larger species.
       Latenivenatrix lived in a very diverse ecosystems,‭ ‬and lived amongst many other dinosaur types including ankylocsaurs,‭ ‬ceratopsians,‭ ‬hadrosaurs,‭ ‬pachycephalosaurs,‭ ‬ornithomomids,‭ ‬oviraptorosaurs,‭ ‬dromaeosaurs and tyrannosaurs.
