Answer:
The climate in that area is different today then when tropical plants and animals lived there
Explanation:
The climate on Earth is constantly changing, and there's numerous factors that contribute to it. The climate can shift from being warm and wet, to cold and dry relatively quickly, thus changing the flora, fauna, and the landscape as a whole. It is no wonder that tropical plants and animals are found in the fossil records in the northern part of Texas, as in the past this region has been dominated by warm and wet climate. That enabled the development of a biome that supported tropical plants and animals. That didn't lasted forever of course, and the climate changed, so Texas became a place with more temperate climate with relatively small amount of precipitation, resulting in changes of what types of animals and plants live there.
