Whats the general characteristics of the smilodon?
IT is a Prehistoric mammal that eats meat, and has sandy brown fur and sabor like teeth, but is not a sabor tooth.
Wait, what?! Sandy brown fur?! How do you know?! And practically any random cat-like mammal with saber teeth is a Saber-tooth. I think.

A paleontologist (pay-lee-un-TAH-lah-jist) studies the fossils of dinosaurs.
What is the smallest dinosaur?
Most palaeontologists believe compsognathus was the smallest dinosaur, but recent discoveries of an a dinosaur, micropachycephalosaurus that may be the smallest dinosaur ever and has the longest name ever given to a dinosaur!
The smallest dinosaur is said to be the compsognathus.Its just 2 feet long and weighs only up to 6.5 pounds. There are a few more small dinosaurs which have the same heeight of the compsognathus.They are the saltopus and the echinodon.
The first dinosaur footprints were found in the Late Triassic Period, around 231 million years ago. The fossil discovered on Vega Island in 2009 likely belonged to a Late Cretaceous dinosaur, dating back to around 66 million years ago.
A list of some known dinosaurs.
Note that there are actually over 700 species of discovered dinosaurs. Only 540 of them currently have official names. The others are awaiting naming.
There are also at least a further 900-1500 species that are currently undiscovered in the Earth's crusts or will never be discovered due to their fossils being destroyed completely by human activity or Earth's surface changes.

When did different fossils including dinosaurs appear?
Fossils appeared continually throughout the history of life; the oldest known fossils are of stromatolites which are thought to be 3.4 billion years old Dinosaur fossils have doubtless been dug up for hundreds of years. The Chinese found "dragon" bones over 2000 years ago - these may well have been dinosaur fossils. In 1676, a large femur was found in England by Reverend Plot - probably from a dinosaur. A report of this find was published by Brookes in 1763.
The first dinosaur to be described scientifically was Megalosaurus; named in 1824, by William Buckland. Buckland (1784-1856) was a British fossil hunter and clergyman who collected fossils. The first dinosaur fossil that was found and described was an iguanadon, but this was described after the megalosaurus.
How did the supercontinent change to seven continents in the time of the dinosaurs?
The supercontinent of Pangea began to rift and break apart between 175-200 million years ago. At first it separated into two landmasses, Laurasia and Gondwanaland. Laurasia separated into Asia, Europe, and North America, while Gondwanaland separated into South America, Africa, Australia, and Antarctica.This was all due to plate tectonics pulling apart the continents.
What did dinosaurs evolve from?
Dinosaurs evolved from reptiles during the Triassic period, about 230 million years ago. They are thought to have descended from Archosaurs, a group of reptiles that also gave rise to crocodiles and birds.
What a time period of birds reproduction?
Birds typically reproduce during specific times of the year based on their species and location. Many birds breed in the spring and summer when food availability is high, temperatures are warmer, and daylight hours are longer. Some species may also breed during other seasons depending on factors like migration patterns and nesting habits.
There has been research done that indicates that birds have evolved from dinosaurs. and mounting evidence shows that theropod dinosaurs are the ancestors of birds. Evidence includes countless skeletal similarities and evidence of feathers in many fossils. Feathers were thought to originally developed for warmth, and eventually evolved into flight aids.
In face of this many scientists do consider birds to be descended from dinosaurs, if not a branch of them.
Answer:Birds do have many features in common with theropods (bipedal carnivorous dinosaurs) which suggests that they had a common ancestor. We dont know that this common ancestor was a dinosaur though. It may well have been a bird (see related links).Looking back in time through the theropod fossil record, these dinosaurs appear to be more bird-like the further back in time you look. Raptors are known to have had feathers and were fairly bird-like, but Archaeopteryx was much more bird-like and lived much earlier and may have been an ancestor of the raptors. There is also a controversial fossil called Protoavis that was dated even earlier and was more bird-like still, with hollow bones like modern birds.
So birds may have been around throughout the mesozoic era and even pre-date the dinosaurs. We have little record of them though because their hollow bones decompose very easily so are less likely to leave fossils. We do have some very ancient bird footprints though (see 3rd link).
It may be more accurate to call the theropods flightless birds, rather than calling birds dinosaurs.
What is the link between meteors and dinosaurs?
the link is that it is a theory that a huge meteor or comet wiped out the majority of the dinosaurs when it impacted on the earth's surface and caused a huge amount of dust to rise into the air and blocked out the sun which meant that the dinosaurs could not breathe and probably froze to death and the impact would have caused an explosion that would be an equivalent to thousands of atomic bombs going off at once I am not totally sure of the facts but this is a start for you...also I think this is a theory and may not have happened at all unless we have testamony from someone who was around back then...sorry about the pun
How do you get to the dinosaur tracks in Tuba City AZ?
The Tuba City dinosaur track site is located 6 miles east of highway 89 on highway 160. Look for a large home-made sign on the south side of the highway that says "Dinosaur Tracks" (right around mile marker 316). The tracks are located about 600 feet down the dirt road to Moenave that heads north from highway 160. Park by the Jewelry shacks. There is usually someone there that can give you a tour (a tip at the end of the tour is appreciated).
Non-avian dinosaurs existed from around 230 million years ago in the Triassic period until the end of the Cretaceous period, 65 million years ago. The cause of their extinction is most likely an asteroid impact coupled with environmental change.
What is the strongest dinosaur?
TRUE STRONGEST: MR DINOSAUR
STRONGEST DINOSAUR: SUPER ARGENTINOSAURUS
ok now onto the actual list lol.
1:Trex and Giganotasaurus (debatable)
2: Spinosaurus (debatable)
3: Charcarodontosaurus (debatable)
4: Allosarus and triceratops (debatable)
5: Long necked dinosaurs (debatable
6: Hervibores
7: Raptors, smaller dinosaurs
8: Smallest dinosaur ever
9: Prehistoric birds
10: Big birds
11: baby dinosaurs
12: Small birds
13: baby birds
note: I included birds because they are techinically dinosaurs.
In a word, no, but scientists can make educated guesses. The closest living relatives of the dinosaurs are crocodilians and birds, and we can look to the ways they vocalize to give us a hint.
Alligators and crocodiles use their larynxes to communicate—they’ll hiss, groan, and yes, roar (here’s a compilation of their sounds). Dinosaurs might have had larynxes, but since those don’t fossilize, it’s impossible to know for sure. Birds, meanwhile, use an organ called a syrinx, which seems to have evolved after dinosaurs. That might indicate that dinos couldn’t vocalize at all, which would be a bummer.
However, there’s also a possibility that they evolved a unique way to vocalize. For example, based on studying their skulls and inner ears, some have theorized that hadrosaurs used their crests to bellow at each other.
So, they probably didn’t roar, but bellowing can be pretty cool too, right?
What was the first dinosaur to die?
The first dinosaur to die would have been one of the earliest species of dinosaurs that lived during the Triassic period, over 230 million years ago. As more and more dinosaur species evolved, the initial species eventually went extinct. It is not possible to pinpoint the exact species that was the first to die.
How is a dinosaur fossil formed?
by needing extra things or less thing in certain places

First, you must define dumb. If you mean IQ, then yes, some dinosaurs were as dumb as birds and others were even dumber too.
What do you mean "as dumb as birds." Birds are SOOO smart. But other than that, you're pretty much right.

What elements have led scientists to believe that a meteor caused the extinction of the dinosaurs?
It is believed that a meteor striking earth brought about the extinction of the dinosaurs. A huge cloud of dust was cast high into the sky, blocking out the sunlight, and reducing the temperature.
In what era did Guinevere live?
Guinevere is a figure from Arthurian legend, which is believed to have originated in the Middle Ages, specifically the 12th century. However, there is no historical evidence to suggest that she actually lived, as she is a fictional character.
What was the geology like during the Permian period?
Many of earth's marine invertebrates were extinct, and many other species that had evolved on earth were extinct as well, so basically the ecosystem was "rebuilding" after the Permian mass-extinction.
No dinosaurs are not still alive there are some relatives of dinosaurs that have been alive since dinosaurs like alligators and crocodiles even tigers and elephants.
The smartest dinosaurs were as smart as what?
The smartest dinosaurs, such as the Troodon or the Deinonychus, were estimated to be as smart as modern-day birds, with problem-solving abilities and some evidence of social behaviors. However, their intelligence level was not as advanced as modern mammals like apes or dolphins.
How do you think we can live with dinosaurs in harmony?
First, we'd have to learn to live in harmony with the natural environment today. Large animals like dinosaurs would be more vulnerable to the effects of habitat destruction from humans than modern animals.
If we could learn to live in harmony with nature, the question becomes whether we're going back in time to live with them or we're recreating them to live with us. If we brought dinosaurs back and let them roam wild, they would devastate ecosystems until said ecosystems could no longer support them.
If we went back in time to live with them, we might be able to coexist if we treated nature with the utmost respect and left plenty of habitat for the dinosaurs. However, the biggest consideration would be us introducing dangerous microbes to their habitat, or their habitat containing disease to which we have no immunity.
Can you find dinosaur bones in your back yard?
It is highly unlikely to find dinosaur bones in your backyard. Dinosaur bones are typically found in specific geological formations and require specialized knowledge and equipment to excavate and identify. It is more common to find fossils of marine organisms or plants in backyard soil.
