What Class Are Saurischia And Ornithischia Part Of?
Saurischia and Ornithischia are two subclasses within the larger class of dinosaurs known as Dinosauria. Saurischia includes dinosaurs with a lizard-like hip structure, whereas Ornithischia includes dinosaurs with a bird-like hip structure.
7 to 8 metres, or 700 to 800cm, or 7000 to 8000 millimetres
What is the formula for calculating dinosaur speed?
We dont even have Dinosaurs anymore. Why do you ask?
Did the spinosaurus have feathers?
That really depends on how you think dinosaurs were feathered.
You see, we know for a fact that at least all small bipedal dinosaurs had feathers. The dinosaurs in the group Theropoda- the carnivorous dinosaurs and all of their immediate relatives- have the strongest evidence for this, with impressions of feathers running across the whole body and covering even the face and feet. This last year, a small ornithopod related to the hadrosaurs and iguanodonts was found with feather types unlike any found in modern birds.
On the other hand, most of the evidence we have show that Spinosaurus, in terms of lifestyle and anatomy, was closest to the crocodile. It makes sense, considering how the two share a common anscestor at around 270 million BCE. It also makes sense that crocodiles don't have feathers. They aren't very practical in the tropical swamps both parties live in, or at the very least don't serve any purpose the same way they would if they lived on land.
As of 2014, it's unclear if Spinosaurus had feathers. It makes sense in terms of how it relates to other dinosaurs, but not exactly in terms of habits. It is likely either way, but we'll need to further our understanding about how these creatures evolved and how feathers form today if we want a complete picture of the past.
What dinosaur is a carnivorsous?
Most theropods were carnivorous. However, some, such as Therizinosaurus, were herbivorous, and others like Oviraptor and Ornithomimus were omnivores.
Do horses live longer than humans?
they live about the same amount of years. some race horses might live longer because they are in better physical shape, but for the most part, all horses live 20+ years
Dromaeosaur refers to a group of feathered theropod dinosaurs within the family Dromaeosauridae, which lived during the Late Cretaceous period. These agile carnivores, characterized by their distinctive sickle-shaped claws on their second toes, include well-known species like Velociraptor. Dromaeosaurs are often highlighted for their potential intelligence, social behavior, and links to modern birds, showcasing evolutionary traits such as feathers. Their fossil evidence has provided significant insights into the behavior and physiology of theropod dinosaurs.
Not dinosaurs as we traditionally think of them. "Classic" dinosaurs went extinict long before any people were around. However, scientists now know that one group of dinosaurs lives to this day: birds. Birds of various types have long been hunted by humans.
How might dinosaurs have beeen more like birds and unlike reptiles?
Well, most paleontologists think that because alot of raptor type dinosaurs stood like birds. There was also some evidence of feathered-dinosaurs, that looked like birds.
Sarcosuchus was a huge 40 foot long prehistoric crocodile that lived in Northern Africa, about 112 million years ago. It preyed on medium sized dinosaurs that came to the water hole for a drink and it may have come in conflict with large predatory dinosaurs like Suchomimus or maybe even Spinosaurus.
Which dinosaur grew upto 40 meters and weighs upto 100 tons?
Argentinosaurus grew up to 35 meters long and weighed up to 110 tons. The Amphicoelius, a very poorly known dinosaur, mayhave been 40 to 60 meters long, and could have weighed up to 135 tons. However, the only fossils of Amphicoelius, a femur and some vertebrae, were lost. Without more bones, it is impossible to be certain of its size, weight, or proportions.
What are the names of bipedal dinosaurs in the cretaceous era beginning with a?
Some bipdeal dinosaurs from the Cretaceous with names beginning in "A" include:
Achillobator
Austroraptor
Adasaurus
Atrociraptor
Where is the most common place to find a fossil?
All areas underground HAVE AN EVEN CHANce of getting a fossil.
During what time period did the chavin live?
The Chavin civilization lived (flourished) from about 900 B.C. to 200 B.C.... If you are in K12, the answer would be 900 B.C.-200 B.C.
What is a Pteranodons habitat?
Pteranodon lived on the coast of the Western Interior Seaway. The Western Interior Seaway was a subtropical, shallow sea that stretched from what is now the Gulf of Mexico to Hudson Bay, splitting North America in half.
Pteranodon were piscivorous, or fish eating, and would have depended on the abundant waters of the shallow sea for food.
Two kinds of scientists that study dinosaurs?
Add geneticist, trying to decode their genome. A paleontologist and maybe a palebontonist.
