The discovery that the Mystery Fossil was pregnant tells us that the Mystery Fossil came from a species that gave live birth. What do you know about how whales, wolves, or crocodiles carry their babies?

Answer: wolves or whales
Explanation: crocodiles lay eggs, so if the mystery fossil gave live birth it would not be grouped with the crocodiles.
The mystery fossil would belong either to a whale or a wolf.
Fossils may be defined as dead and organic remains of past living organisms which are buried deep in the soil.
The mystery fossil does not belong to a member of the crocodile, because crocodiles lay eggs, and their gender depends on the average temperature.
If a mystery fossil is found to be pregnant at the time of death, it surely belongs either to a whale or a wolf.
Therefore, it is well described above.
