Mesosaurus
They have been not able to spread easily across land because it better adapted the environment and stayed there in water.
<h3>What are Mesosaurus ?</h3>
These creatures were ancient lizards that looked a bit like small crocodiles, with narrow heads and long tails. They had webbed feet and grew to about 1 meter long
- The Mesosaurus might have gone extinct by the end of the Early Permian period. As their fossils were discovered on both sides of the Atlantic Ocean, the species must have become extinct due to continental drift.

Answer:
63, grams
103, grams
Explanation:
According to the Academy of Nutrition and Dietetics endurance athletes, like Margaret needs about 0.55 to 0.9 grams of protein per pound while Strength-athletes that are trying to build muscle mass need more than 0.9 grams of protein per pound.
Since Margret is an Endurance athletic according to the question she will be needing:
115 lb x 0,55 =63,25 grams
115 lb x 0,9 =103,5 grams
Therefore Margaret should consume between 63 and 103 grams of protein daily.
