If a scientist finds the remains of a plant between a rock layer that
contains 400 million-year-old Phacops fossils and a rock layer that contains
230 million-year-old Tropites fossils, how old could the plant fossil be?​

Respuesta :

Answer:

Scientists can infer that the plant existed sometime from 400 million to 230 million years ago

The age of plant fossil is lower than 400 million-year but higher than 230 million-year.

Age of plant fossil

The age of plant fossil occurs between 230 million-year and 400 million-year because the layer in which plant fossil comes between 230 and 400 million-year. The age of that plant fossil is lower than 400 million-year old Phacops fossils due to its presence above the layer.

While on the other hand, the age of plant fossil is higher than 230 million-year due to its occurrence below the layer of 230 million-year old Tropites fossils so we can conclude that the age of plant fossil is lower than 400 million-year but higher than 230 million-year.
