DINOS & DINGOS
Talking about evolution is of course quite fun, but in the end, one of the most important questions is: where are the dinosaurs?!


Rest assured here they are: a very dangerous dinosaur!

Slide 1 - Tekstslide

Arguments for ecolution
When we look at the history of life on Earth, it soon becomes clear that all life comes from one common ancestor. But what kind of evidence did we find for this?

Slide 2 - Tekstslide

Slide 3 - Video

What are examples of evidence for evolution? Summarize the video

Slide 4 - Open vraag

In the film Jurassic Park, an island full of dinosaurs is created by extracting DNA from fossils. Why is this not possible with fossils of dinosaurs that have died out?

Slide 5 - Open vraag

One of the ways we have learned that dinosaurs  are actually the ancestors of birds has to do with a large number of fossils that have been found over the past 25 years. Many of these fossils come from ancient deserts (such as the  GobiDesert).

The bones of birds become fossils much less often than the bones of large predators (such as T-rex or Triceratops). This has to do with the fact that these bones are very fragile; They're hollow.

Slide 6 - Tekstslide

Why do we find few fossils on which the feathers of a bird/bird-like dinosaur can be seen?

Slide 7 - Open vraag

For the next question, watch the video. Here is a clear example of a situation in which a bird-like dinosaur eventually turns into a fossil.

Slide 8 - Tekstslide

Explain why in this situation the dinosaur can turn into a fossil from which we can see the feathers?

Slide 9 - Open vraag

However, it is not necessarily the case that a larger dinosaur leaves more fossil bones. In this video, people talk about  Argentinosaurus  (from Argentina). These animals were more than 25 (this video even says 35) meters long.

Slide 10 - Tekstslide

Why is it hard to find bones from big dinosaurs like Argentinosaurus?

Slide 11 - Open vraag

Would it be relatively easy or difficult for the eggs of an Argentinosaurus to become a fossil? Explain why.

Slide 12 - Open vraag

One of the most common dinosaur bones is that of common- and large - dinosaurs. A good example of this is the 'hadrosaurus'. These animals looked a bit like cows; they were large, ate plants, and often traveled in large herds.

Slide 13 - Tekstslide

Many of their bones are found in places where rivers used to flow. Explain why the bones are found mainly there.
