It always amazed me to think that sharks were that far in-land.

Born and grew up in Dallas TX. As a Boy Scout, we would hike from Camp Wisdom in SW Dallas to Mountain Creek Lake on the W edge of Dallas next to Grand Prairie. Our destination at the lake was called “Sharks Tooth”, and was a mound of dark dirt that we would dig into and find teeth. ...I still have one over an inch long that I found there over 60 years ago.
This area is around 300 miles NORTH of the Gulf of Mexico at Galveston TX, and is further evidence that the ocean waters once covered the land here in North Central Texas.
Fascinating. I have seen maps of Florida’s coastlines through the ages, but never Texas’. At one point Florida was completely underwater except for the panhandle. I’ve heard Florida described as being like a cork floating on the water. It would be interesting to see a world map of the coastlines of all countries over the millennia.
