Which RAPTOR is Actually in Jurassic Park? (Hint: IT'S NOT VELOCIRAPTOR)
TLDRThe video script provides an in-depth exploration of the maniraptoran dinosaurs, a fascinating group of theropods closely related to modern birds. It discusses the misconceptions surrounding the portrayal of 'velociraptors' in the Jurassic Park franchise, explaining that the actual species featured was likely Deinonychus, known for its large, curved claws. The video delves into various subgroups of maniraptorans, including Therizinosauria, Alvarezsauria, Oviraptorosauria, and the true dromeosaurids, highlighting their unique characteristics and the evolutionary links to avialans, the group encompassing modern birds. The script also touches on the debate over the classification of these dinosaurs and the scientific community's evolving understanding of their biology and behavior.
Takeaways
- ๐ฆ Dinosaurs are a distinct lineage of reptiles, with crocodilians being their closest relatives among living reptiles.

Q & A
What is the significance of the movie 'Jurassic Park' in the narrator's life?
-The movie 'Jurassic Park' was a significant event in the narrator's life as it introduced them to the velociraptor, a dinosaur that became one of their absolute favorites, and further fueled their passion for dinosaurs.
What is the correct term for the group of dinosaurs that includes the velociraptor and the one depicted in the 'Jurassic Park' movies?
-The correct term for the group of dinosaurs that includes the velociraptor and the one depicted in the 'Jurassic Park' movies is Maniraptora.
What is a common misconception about dinosaurs?
-A common misconception is that all ancient reptiles were dinosaurs. In reality, many ancient lineages of reptiles coexisted with dinosaurs, and some are still alive today, such as turtles, crocodilians, and lizards.
How are dinosaurs related to crocodilians?
-Dinosaurs are more closely related to crocodilians than crocodilians are to any other group of extant reptiles. Both dinosaurs and crocodilians are part of the Archosaurian clade of diapsid reptiles.
What is unique about the forelimbs of maniraptoran dinosaurs?
-Maniraptoran dinosaurs have very large and dexterous forelimbs, with the name Maniraptora meaning 'hand thief' or 'hand plunderer.' They typically have three fingers, a large bony sternum, and half-moon shaped bones in their wrists.
Which group of dinosaurs is most closely related to birds?
-The group of dinosaurs most closely related to birds is the Paraves, which includes modern birds as well as other dinosaurs that share a close relationship with the avialans.
What is the significance of the term 'Therizinosauria'?
-Therizinosauria is a group of dinosaurs named after the genus Therizinosaurus, which means 'reaper' or 'sickle lizard.' This name is derived from the intimidating, sickle-like claws on their front limbs, which were likely used for stripping leaves from trees.
What is the role of the Patreon supporters in the creation of the video content?
-Patreon supporters play a crucial role by providing financial support that allows the creators to research, produce, and experiment with content like the video about maniraptoran dinosaurs.
Why were the dinosaurs in 'Jurassic Park' not accurately named velociraptors?
-The dinosaurs in 'Jurassic Park' were not accurately named velociraptors because paleo-artist Gregory S. Paul suggested that the Mongolian velociraptor and the North American Deinonychus were similar enough to be classified in the same genus, with the earlier known genus being 'Velociraptor.' This influenced Michael Crichton's depiction in the book, but the scientific community did not widely accept this classification.
What is the significance of the Deinonychus in the 'Jurassic Park' franchise?
-Deinonychus is significant because it was the dinosaur species that the 'Jurassic Park' velociraptors were based on, despite being incorrectly named. It had the right size, head shape, and was found in the correct geographic location to match the depiction in the movie.
What are the key characteristics of Dromaeosaurids?
-Dromaeosaurids, or running lizards, are characterized by being bipedal, having large sickle-shaped claws on their inner toe, and likely being heavily feathered. Some species, like Microraptor, may have been capable of powered flight, and they generally had forward-pointing eyes for better binocular vision and depth perception.
Outlines
๐ฆ Introduction to Maniraptoran Dinosaurs
The video begins with an introduction to dinosaurs, highlighting the velociraptor as a favorite. It clarifies that not all ancient reptiles were dinosaurs and distinguishes dinosaurs as a unique reptilian lineage. The theropod clade, which includes maniraptoran dinosaurs like the velociraptor, is discussed, along with their physical characteristics such as large forelimbs and a bony sternum. The video also corrects the misconception that velociraptors were featured in the Jurassic Park movies, and thanks patrons for their support.
๐ฆ Exploring Maniraptoran Clades
This paragraph delves into various clades of maniraptoran dinosaurs, including Therizinosauria, known for their sickle-like claws, and Alvarezsauria, which are small and had fused wrist bones. Oviraptorosauria are described as having beaked faces and are speculated to have fed on insects. The paragraph also discusses the group most closely related to birds, the Paraves, which includes the famous velociraptor and its portrayal in Jurassic Park. The narrative touches on the hunting methods and physical adaptations of these dinosaurs.
๐ฆ The True Nature of 'Velociraptors'
The script clarifies the confusion surrounding the velociraptor's portrayal in Jurassic Park, explaining that the actual species depicted was Deinonychus, not a velociraptor. It details the physical attributes of Deinonychus, including its size, head shape, and the formidable claw on its foot. The video also discusses the scientific debate over the classification of these dinosaurs, particularly the influence of Gregory S. Paul's work on the Jurassic Park franchise.
๐ฆ The Avialae Clade and Modern Birds
The final paragraph focuses on the Avialae clade, which includes modern birds and other dinosaurs more closely related to birds than to Deinonychus. It mentions Archaeopteryx and the Enantiornithes, a group of birds with a convergence on the bird body form. The paragraph emphasizes the evolutionary success of this group, which survived the mass extinction event at the end of the Cretaceous period. It concludes with a prompt for viewers to decide which group of dinosaurs should be covered next.
๐ฌ A Reflective Conclusion and Humorous Aside
The video concludes with a humorous speculation about the intelligence of dinosaurs, suggesting they might have been capable of space travel and the use of asteroids as weapons. It playfully challenges the viewer to imagine such a scenario, ending on a light-hearted note that invites further engagement and speculation from the audience.

Maniraptoran dinosaurs, including the Velociraptor, are known for their large and dexterous forelimbs, with the name meaning 'hand thief' or 'hand plunderer'.
Maniraptorans are part of the Theropod clade, which includes iconic dinosaurs like the Tyrannosaurus Rex.
Maniraptorans are unique among dinosaurs for having a keeled sternum and wrist bones similar to birds, indicating a close evolutionary relationship with avialans.
Therizinosauria, named for their sickle-like claws, were likely herbivores and ranged in size from seven feet to over 30 feet.

Oviraptorosauria had short, beaked faces and are thought to have fed on a variety of food sources, though their exact diet remains a mystery.
The group Parves, closely related to birds, includes the Velociraptor and other similar dinosaurs, many of which were carnivorous.
Scansoriopterygidae, known as 'climbing wings,' were the first in their group to show adaptations for an arboreal and somewhat flighted lifestyle.
Dromaeosaurids, including the Velociraptor, were bipedal with large sickle-shaped claws and likely had better binocular vision than most dinosaurs.
Troodontids, relatives of Dromaeosaurids, were lightly built with closely spaced teeth, suggesting they preyed on smaller animals.
