Pathological Otodus 2.31"

This rare pathological Otodus with split tip.

The Otodus, specifically Otodus obliquus, is an extinct species of mackerel that lived approximately during the Paleocene and Eocene epochs, roughly 60 to 40 million years ago. This animal is known for its large size and is one of the early ancestors of the famous Megalodon. Here are some key characteristics and facts about the Otodus shark:

1. Size and Appearance: Otodus obliquus was notably large, with estimates suggesting it could grow up to 30 feet (9.1 meters) in length. It had a robust body and large, triangular teeth with smooth cutting edges. The teeth are often the most common fossils found and are a significant indicator of its size and predatory nature.

2. Teeth and Diet: The teeth of the Otodus shark were large, with some specimens measuring over four inches in length. These teeth were likely used to catch large prey, including fish and possibly marine mammals.

3. Habitat and Range: Otodus obliquus is believed to have inhabited warm, shallow seas. Fossil evidence has been found in various locations around the world, including North America, Europe, Africa, and Asia, indicating a wide geographic range.

4. Evolutionary Significance: Otodus obliquus is an important species in the study of shark evolution. It is considered to be an ancestor of many larger and more famous prehistoric sharks, including the Megalodon (Carcharocles megalodon). Its evolutionary lineage shows the development of large predatory sharks in the Earth's oceans.

5. Fossil Record: The fossil record of Otodus obliquus is primarily composed of its teeth, as shark skeletons are made of cartilage, which does not fossilize as well as bone. These teeth are a common find in certain fossil formations and are popular among collectors.

The study of Otodus obliquus helps scientists understand the early evolution of large predatory sharks and the ecological roles they played in ancient oceans. Its large size and widespread presence make it a notable species in the history of marine life.
