Large rods traveled northeastern British Columbia. An article published in Historical Biology presenting the most detailed fossils reported on giant crocodilians. The sites are from the Peace Region of southeastern British Columbia, north of Tumbler Ridge.

They are located in swimming pools, which are made when soldiers gather dirt from lakes and rivers with their claws. Some of these swimming pools showed amazing detail, with various lines showing the scales on the legs of the coral.

While Tumbler Ridge is famous for its dinosaur songs, there is something special about crocodiles. Unlike dinosaurs, they survived, but have not changed much since the Mesozoic.

By 2020, a crane company will have the time and staff to return four large blocks that have some of the best examples of these tracks and styles. They were taken to the Tumbler Ridge Museum, where they were preserved and included in future exhibitions.

Old giant

The songs and poems we have examined are in the year 95-97 million years from the Cretaceous Period. Along the way are ankylosaurs, ornithopods and turtles.

Most crocodiles can be counted from the distance between their claws. We used this distance to estimate the body length to be about nine meters, or up to 12 meters. This was confirmed by the fact that we saw a road, 75 centimeters long, which was allowed for a similar length of about nine meters.

The weight of such a large size was about five tons, which was probably the top thief. By comparison, the longest history of crocodiles alive today is about six meters.

Gigantism has often been mentioned in crocodiles in fossil history. In North America, Deinosuchus is the oldest fossil record of crocodiles at about 82 million years old, estimated to be between 8 and 12 meters long. Deinosuchus was captured from the United States and Mexico, but not from Canada.

Large swimming pools from north of Tumbler Ridge show the first appearance of Deinosuchus, which lived about 13 million years before the first appearance of large crocodiles in the United States.

Observing environmental changes

The region is located on a low plateau with shallow lakes, rivers and lush plains, located about 100 kilometers inland from the shores of the Western Interior Seaway that connects the Gulf of Mexico with the Arctic Ocean.

Many streams of water can be recorded, which will determine whether the animals walk or swim. This helped to explain the types of music and the traditions that were seen.

Based on these findings, we are able to find 112 million years old swimming traces, created by very small crocodilians (between one and two meters in length) in the Tumbler Ridge UNESCO Global Geopark. . Our familiarity with the nature of the well -kept species from near Tumbler Ridge led directly to the first discovery of crocodile swimming pools in Africa.

The coexistence of traces created by walking ankylosaurs and swimming crocodiles in the same skin is interesting and unknown in fossil history. One of the ankylosaur trails is the smallest unexplored from the country. The songs, made by a young boy, were only 10 centimeters wide.
