While out riding we came across some dinosaur tracks. Here is some information about the dinosaurs tracks if you are interested. We found them in a one of the many sandy washes found in the area. This is what the sign said about it:
Exposed in the wash are dinosaur trackways which document the passage of at least two different types of dinosaurs. The trackways are exposed in the Moenave Formation, a floodplain deposit more than 200 million years old. These trackways are some of the best examples of their age found in western North America. Although the exact identity of the dinosaurs which made these footrints may never be known (no skeletal remains are found in association), both types walked erect. The larger tracks were probable left by a large herbivore (such as a prosouropod) believed to be 20 feet long and weighing 8-10 tons. The smaller dinosaur, likely a carnivore (coelurosaur), was estimated at 10 feet long and 100 pounds. Scientific Study is continuing on these footprints and the surrounding rocks to learn as much as possible about the prehistoric event recorded here. The Coelurosaur
Coelurosauria is a diverse group of theropod dinosaurs that include tyrannosaurs, ornithomimosaurs, and maniraptors;
Maniraptora includes birds, the only coelurosaurs alive today. All feathered dinosaurs discovered so far have been coelurosaurs; in fact, some scientists believe that most members of coelurosauria bore some kind of feathers. Fossil range is middle Jurassic to late Cretaceous.
The Prosauropoda
Prosauropoda were a group of early herbivorous dinosaurs that lived during the Triassic and early Jurassic periods. They were frequently the predominant herbivore in their environment, and quickly reached large size. All prosauropods had a long neck and a small head, forelimbs shorter than hindlimbs, and a very large thumb claw for defense. Most were semibipedal, although at least one large form was fully quadrupedal. They were originally thought to be the ancestors of the sauropods, but are now considered parallel lineage.

That's not nerdy. Well, even if it is, we found it very interesting. I can totally see Tim going out to motorbike and being way more amused by the science around him. You two need to hang out. Tell Laura to tell you about salamanders. She read all about them in this english class at Ricks.
U r sooo weird but i still love u!!
