The dinosaurs that walked along algae-covered mud flats left deep footprints . Those tracks were subsequently filled in and covered by sediments. Mineral-rich water seeping into the mud, along with heat and pressure of the overburden gradually turned them to stone.
The dinosaurs that made the tracks are believed to be Acrocanthosaurus and Iguanodon, and lived during the Cretaceous Period. There is also a large snail that made its tracks next to the two dinosaurs. The tracks are embedded in limestone and are slowly eroding away. The Heritage Museum has built a huge cover over the tracks to keep the weather off of them. The Museum has over 350 preserved dinosaur tracks, estimated to be over 108 million years old.
There may be more, but so far we have seen the Largest Recorded Live Oak Tree in Texas, located in Lamar, near Rockport, Texas, calculated to be about 1,000 years old, and the 2nd Largest Recorded Live Oak Tree, located in Columbus, Texas. I figure it was "born" about 1516.
This massive tree is recognized by the Texas Forest Service among their "Registry of Champion Big Trees." It is thought to be about 500 years old with a score of 413 on the index scoring system. This score combines the tree's circumference, height and one-fourth of the average crown spread. It measures 75 feet tall, 310 feet in circumference, and a crown spread of 111 feet. It is one big tree.
