Where one sees a hole in the skull, there was often muscle in the living head, particularly in the skills of the big meat-eaters. Other holes (or "voids") may be sinuses and spaces in general served to lighten the head, fairly important if the creature has it on the end of a long, long neck. By the way, we distinquish the larger group to which dinosaurs belonged (Diapsidae) by the fact that the skulls all have two particular holes, whereas the creatures ancestral to the mammals have only one.
What else can I help you with?
Why are dinosaurs endangered?
dinosaurs are extinct not endangered
Were most dinosaurs Carnivores or Herbivores?
Most dinosaurs were herbivores, meaning they primarily ate plants. However, there were also many species of carnivorous dinosaurs that hunted and fed on other animals. The balance between herbivorous and carnivorous dinosaurs varied between different species and ecosystems.
When did dinosaur's go extinct?
Dinosaurs became extinct 65 million years ago, at the end of the Cretaceous period.
How many foramen are there in the body?
There are numerous foramen in the human body, located within different bones and tissues. These openings provide passages for nerves, blood vessels, and other structures to pass through. Some examples include the foramen magnum at the base of the skull and the intervertebral foramina in the spinal column.
What will probably be without the dinosaurs extinct?
For one thing, humans wouldn't exist. If the dinosaurs had survived, the small mammals that would have eventually evolved into humans wouldn't have had the chance. Most large mammals - lions, elephants, moose, kangaroos, etc. - wouldn't have had the chance to evolve either. All the big, widespread species would be reptiles or birds.
Are there dinosaurs in Russia?
Obviously, there were many dinosaurs in Russia, including Orolotitan, a large hadrosaur with a club-shaped crest. Also, many dinosaurs common to Asia are probably existent in Russia, too.
What evidence shows what allosaurus' eat?
First, there is the skull shape and the large, curved, pointed, serrated teeth. The large skull is adapted to delivering mortal bite wounds, and the teeth are perfect for killing as well as shearing flesh off of a carcass. Allosaurus teeth couldn't be used effectively for eating plants. In addition, there are many fossil bones of herbivorous dinosaurs that bear tooth marks from Allosaurus.
Do other dinosaurs eat them?
One clade of dinosaurs, the theropods, were carnivorous. Many of them were large and ate other dinosaurs. Today, birds are the only surviving group of dinosaurs. Some birds of prey eat other birds, so dinosaurs still eat other dinosaurs today.
How many large bones are in the skull and which is its only movable bone?
the only movable bone is the mandible (jaw)
What the different between dinosaurs and birds?
While birds and dinosaurs share many similarities, the key differences lie in their skeletal structures. Dinosaurs have a more primitive structure, with separate openings for breathing and eating, while birds have a more advanced respiratory system that allows for efficient airflow. Additionally, birds have evolved lightweight bones and feathers for flight, traits that are not found in dinosaurs.
What was the purpose of the existence of dinosaurs?
Dinosaurs filled many niches in their habitats. Many were large herbivores, preventing plant overgrowth. Others were carnivores or insectivores, preventing prey animals from overpopulating. The dinosaurs that still exist, birds, fill many niches, including spreading seeds, insect and rodent control, and pollinating flowers.
If scientists were to find a large crater dated around the time of the dinosaurs what might it indicate about their extinction?
Many people actually believe that A large flood killed all of the dinosaurs, A large earthquake caused the crater that engulfed the dinosaurs, or A large volcanic eruption resulted in global climate change., but no. it was actually that of A large asteroid strike resulted in a massive explosion that altered plant life. It created an explosion so big that it basicly wipes out the entire species of dinosours!
Why are dinosaurs endangered?
dinosaurs are extinct not endangered
How might the mass extinction of dinosaurs enable many new species of mammals to develop?
Mammals no longer succumbed to carnivorous dinosaurs as prey and they no longer had to compete with dinosaurs for common food/resources.
Why are there so many holes in the skull?
The holes in the skull, known as foramina, serve various important functions. They allow for the passage of nerves, blood vessels, and other structures between the brain and other parts of the body. These openings are essential for communication and the supply of nutrients, as well as for the regulation of bodily functions. Additionally, they contribute to the overall lightweight structure of the skull while still providing protection for the brain.
Where can developer jobs be found?
Developer jobs can generally be found in any large city. Most companies need at least a couple developers at their company, and in large cities there will be many job openings.
How many sea dinosaurs are there?
When the dinosaurs lived there were sea monsters but they were called marine reptiles and were not dinosaurs.
