In recent months in the US state of Texas Dinosaur Valley State ParkTraces of dinosaurs have been found that are 113 million years old. It has been announced that these tracks, created by drought, belong to a dinosaur species called “Acrocanthosaurus”.

The dinosaur was estimated to have an average length of 5 meters and a weight of 7 tons. This is where 60 out of 140 look comfortable your footprints The fact that it has remained intact all these years surprised everyone.

So how come these traces reach the present time without deteriorating?

When creatures step on a muddy road, the ground under their feet or hands is compressed by the pressure. Footprints can reach several layers. Over time, the insides of these footprints are small. with pebbles or sand dollars. After a while, the filled spots start to petrify.

petrified footprints millions of years can be protected and people cannot notice them because of the layers on them. That is, until it protrudes above the ground under the influence of drought.

There are several factors that cause footprints to turn into fossils.

The consistency and density of the soil affects the shape, size and depth of footprints. The setting for a flawless course too hard or soft shouldn’t exist.

If the ground is very hard, the pressure will be unclear. It doesn’t show details and doesn’t give much information about what the shape looks like. If the soil is too soft, tracks can easily be deformed or it can collapse in on itself.

What do dinosaur footprints tell us?

Dinosaur footprints are one of a kind. is a fossil. These traces are evidence of their activity during life, but they are not part of it. By looking at these tracks, scientists can guess which dinosaur group they belonged to by examining their size and shape. In addition, they can recognize when they are on two feet or on all fours.

Archaeologists try to make guesses from traces, geographic location and age of surrounding rocks They can also make more accurate predictions by taking it into account
