Dromaeosaurus (/ ˌ d r oʊ m i ə ˈ s ɔːr ə s,-m i. oʊ-/; [3] lit. ' running lizard ') is a genus of dromaeosaurid theropod dinosaur that lived during the Late Cretaceous period (middle late Campanian and Maastrichtian), sometime between 80 and 69 million years ago, in Alberta, Canada and the western United States.
Discoveries of feathered dromaeosaurids continued into the 2000s. Xu, Zhou, and Wang named the new genus Microraptor in 2000. [6] Three years later, Xu and others would report a new species in this genus that exhibited a bizarre "four winged" body plan with long pennaceous flight feathers on both its front and hind limbs.

Since Microraptor and other dromaeosaurids possessed feathers, it is reasonable to assume that this trait was present in all of Dromaeosauridae. Feathers were very unlikely to have evolved more than once, so assuming that any given dromaeosaurid, such as Utahraptor , lacked feathers would require positive evidence that they did not have them ...
Symptoms to note: Bee stings cause moderate pain, which should subside within a few hours. All insect stings can cause life-threatening allergic reactions, and bee stings are no exception.
Maniraptora is the only dinosaur group known to include flying members, though how far back in this lineage flight extends is controversial. Powered and/or gliding flight is believed to have been present in some types of non-avialan paravians, including dromaeosaurids, such as Rahonavis and Microraptor. [7]
Indiana Dunes National Park is a National Park Service unit on the shore of Lake Michigan in Indiana, United States. A BioBlitz took place there on May 15 and 16, 2009. [1] During that time, a list of organisms was compiled which included a preliminary list of the reptiles of the area. [2] Turtles (Testudinate)
