All living things on Earth contain carbon in that most of the molecules in us include carbon atoms. Dinosaurs were living creatures and are like all living creatures today in this respect.
Like most fossils, dinosaur fossils have been mostly replaced with minerals and are not made of the original material. However, many contain trace amounts of original material. Some even contain proteins from the dinosaur.
Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
First and most. There is not much dinosaur anything to be found. Carbon that we are getting our fuel oils from is mainly made from very old plants that are now sitting about 7 miles down. Mostly it is made into fuel and plastic. There may be things made from dinosaur carbon (as rare and perhaps undefinable as having come from a dinosaur or plant) that we some how would get in our bodies and stay there but I don't know what that is. All life is recycled. Maybe what was in a dinosaur is in humans. It may not be knowable.
In general organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions).
Yes, all organic molecules contain carbon.
There are many objects in the world that contain carbon. Some items are seashells, pencils, fabrics, wood, carbonated sodas, and water.
organic ones
Ultrapure water doesn't contain impurities.Impure water may contain ammonia (as ammonium), carbon dioxide and carbon as some organic impurities; but not proteins.
Basically, organic compounds have carbon. Inorganic do not (though there are some exceptions)
Limestone is composed of calcium carbonate, CaCO3 (the 3 is a sub-script) so it's a calcium atom, a carbon atom, and 3 oxygen atoms. There are some other minerals that contain carbon as well. Diamond, which is pure carbon, is an example.
its not hydrogen that makes a compound organic but carbon. With a few exceptions, compounds that contain the element carbon are organic compounds. Some common exceptions are, CO2, CO, all carbonates as well as all the allotropes of carbon.
If you could eat a dinosaur, which is impossible as they are now extinct, you would be able to eat some of them if they were cooked as 90% of dinosaurs were no bigger than a chicken. Some of the big ones however...
