Why did the dinosaurs that dominated the earth for 170,000,000 years suddenly become extinct?
Volcanic eruptions? Or a meteorite hitting the earth?
The answers don’t just lie in encyclopedias.
Although dinosaurs have been extinct for a long time, and no one has seen their true colors with their own eyes, our understanding of
the types and habits of dinosaurs is getting richer and richer, which is due to the archaeological excavation of dinosaur fossils by paleontologists.
Scientists can roughly restore the shape and living conditions of dinosaurs through dinosaur fossils.
So we can only see the restored dinosaur world in many movies and books, which can be said to be a feast for the eyes.
Do you want to know what it’s like to discover dinosaur fossils?
This time, let’s turn into little archaeologists and do it ourselves to truly reproduce the process of archaeologists discovering, excavating and restoring dinosaur fossils…
Clear water, fossil models, digging tools.
First, break the fossil model with a small hammer;
Then add a glass of water to soften the model and prevent dust;
Then use it together with a chisel to slowly excavate dinosaur fossils;
Use a brush to clean the powder on the dinosaur fossils to remove the bone lines.
Finally, clean up the excavated dinosaur fossils and arrange them neatly.
Observe the bone structure of dinosaurs, use your brains, and put together dinosaur fossils.
After completing the restoration work, you can get ultra-realistic and complete dinosaur fossils, just like those treasured in museums.
How did dinosaur fossils form?
Dinosaur fossils refer to the fact that the soft tissues in the body of dinosaurs disappear due to decay after death,
and the hard tissues such as bones (including teeth) are deposited in the sand and are in an oxygen-isolated environment.
After tens of millions or even hundreds of millions of years of deposition role, the bone is completely mineralized and preserved.
In addition, the relics of dinosaur life, such as footprints, can also be petrified and preserved as fossils.
The dinosaurs that can be seen in museums are actually only a small part of the fossil inventory.
For example, the Earth Science Museum at Brigham Young University in Provo, Utah, houses nearly 100 tons of fossils that have not yet been stripped of their gypsum shells.
Some paleontologists will identify entirely new species of dinosaurs from one or two unstudied or misidentified bones unearthed a century ago.
