Why are the fossils of vertebrates similar to the bones of living vertebrates?
Fossils of vertebrates are similar to the bones of living vertebrates because they were once part of living organisms that shared similar anatomical structures and functions. Over time, the bones of vertebrates have undergone evolutionary changes, but many core features have been conserved due to their essential functions. This similarity allows paleontologists to make informed comparisons and infer the evolutionary relationships between ancient and modern vertebrates.
When you compare the dinosaur fossil to modern day vertebrates what does it most resemble?
Dinosaurs most resemble birds and reptiles but mainly birds because birds evolved from dinosaurs.
What is an abelisaurid?
An abelisaurid is a dinosaur of the Cretaceous period, whose fossils have been found on the modern-day continents of Africa and South America, as well as the island of Madagascar.
Are dinosaur bones radioactive and if so, what implications does this have for studying and preserving these ancient fossils?
Dinosaur bones are not inherently radioactive, but they can sometimes contain trace amounts of radioactive elements. This can complicate dating methods using radioactive isotopes, but modern techniques can still accurately date fossils. In terms of preservation, the presence of radioactivity in dinosaur bones does not pose a significant risk as long as proper safety measures are followed during handling and storage.
Who studied dinosaur fossils how could they now this?
Paleontologists study dinosaur fossils to understand their biology, behavior, and evolution. They analyze fossilized remains, including bones, teeth, and footprints, using techniques such as radiographic imaging and isotopic analysis. By comparing these fossils to modern animals and employing geological context, they can reconstruct the environments dinosaurs lived in and infer their lifestyles. This multidisciplinary approach allows researchers to piece together the history of these ancient creatures.
What dinosaur is a carnivors?
The bipedal ( walked about on two feet) Dinosaurs such as the Tyrannosaurus Rex and the Allosaurus were , as judged from fossils, aggressive, carnivorous, that is meat-eating and led a life style like modern carnivorous mammals- If it moves it might be something to eat! The Trachodont or duckbill ( many fine fossils survive) is believed to have been herbivorous ( plant-eating) in habit.) The Pterodactyls, which are NOT strictly speaking dinosaurs- were carnivorous and some went after fish- as do some modern day Bats.
Why is it possible to find dinosaur fossils?
It is possible to find dinosaur fossils because maybe about 100,000,000 years ago God made dinosaurs .he made some that eats other dinosaurs that they cannot eat the bones . Some dinosaurs were just killed by maybe cave men and maybe other sort of creatures. Or maybe they were to old to live and they died by oldness. The dirt covered their bones that in this modern they we call them now fossils. Or such now scientists call them .
From what dinosaur did cats evolve?
Cats did not evolve from dinosaurs. Cats evolved from a common ancestor of modern carnivores, which lived after the extinction of dinosaurs.
How many days ago did the dinosaurs live?
Dinosaurs existed 65.5 million years ago. Back then, a day was about 23 hours. Saying that an average day between modern times and the dinosaur age was 23.5 hours, and a year is 365.25 x 24 hours, then the dinosaurs died out about 24,431,500,000 days ago.
Why do some scientist believe that dinosaurs were warm blooded?
There are a number of indicators. Some dinosaur fossils show indications of an active lifestyle that a cold-blooded animal is unlikely to have. One dinosaur was found to have had a four-chambered heart, which is also found in mammals and birds, but not in modern reptiles.
Where can you buy Australian dinosaur hatching eggs?
You shouldn't be buying actual dinosaur fossils at all, since they are an extremely rare and limited natural resource which can never be renewed. Every time someone buys or destroys a dinosaur fossil, the scientific value that fossil has is essentially ruined and anything we could have learned from it is lost. Also, it is IMPOSSIBLE to get a hatching dinosaur egg (unless you're looking for a modern bird) because dinosaurs are extinct, except for birds.
How are vertebrates grouped?
Vertebrates were once grouped according to their size before modern taxonomy was founded. Even invertebrates.
