I think it might be erosion because erosion breaks down objects
Two people from completely different cultures can come together and reproduce and their children or child could be classified in both culture groups.
The correct answer is - False.
The trilobites are a marine type of animal that has been one of the most successful animals in the earlier stages of the history of life on this planet. They have existed for roughly 270 million years, from approximately 521 million years ago until 252 million years ago. Their beginnings are traced back in the Early Cambrian period, and they went extinct in the great mass extinction at the end of the Permian period.
So, the trilobites are a very common fossil in the time frame from 521 million years ago until 252 million years ago, but they went extinct than, so they are missing from the fossil records onward from that time, thus we can say that they are not common throughout the entire fossil record.
In this question, we are not provided with the image of the dinosaur track. Because of this, we are unable to tell whether this specific track is right-side up or upside-down. However, we can give you some guidance so that you can identify this on your own.
In general, in this type of prints, mud cracks extend downward into soft sediment. These cracks mean that when more sediment is washed in, the second layer fills the cracks beneath. Afterwards, once the layers have hardened, the rock may be cracked apart. Based on this, we can conclude that if you see troughs in a mud-crack pattern, you re looking at the second layer, which was originally right-side up.
