Cretaceous Crocodylian Unearthed in North Arlington, Texas

Discovery of a 100-Million-Year-Old Fossil

In North Arlington, Texas, a remarkable paleontological discovery has been made at a Cretaceous fossil site. University of Texas at Arlington paleontologists have uncovered the remains of a crocodylian that lived approximately 100 million years ago.

Texas’s Ancient River Ecosystem

During the Cretaceous period, Texas was home to a vast river ecosystem that flowed into a seaway spanning the middle of North America. This ecosystem was teeming with life, including turtles, sharks, lungfish, and the dinosaur Protohadros, which grazed on vegetation along the shoreline.

The Crocodylian’s Role

The newly discovered crocodylian likely preyed upon the abundant fish in this river ecosystem. However, its exact species is yet to be determined.

Woodbinesuchus and the Mystery Fossil

One known crocodylian species present at the North Arlington site is Woodbinesuchus. However, researchers have identified crocodylian fossils that do not match Woodbinesuchus, suggesting the potential for a new species discovery.

Paleontological Significance

The discovery of this new crocodylian fossil provides valuable insights into the diversity and ecology of Cretaceous crocodylians in North America. It also highlights the rich paleontological heritage of Texas and the importance of preserving and studying such sites.

Ongoing Research

Paleontologists are eagerly awaiting further analysis of the fossil to determine its species and shed light on the evolutionary relationships within the crocodylian lineage.

Cretaceous Fossil Site: A Window to the Past

The Cretaceous fossil site in North Arlington serves as a remarkable window into the ancient world. It offers a glimpse into the diverse ecosystem that existed millions of years ago, providing invaluable information about the evolution of life on Earth.

Additional Findings

In addition to the crocodylian fossil, paleontologists have discovered numerous other fossils at the North Arlington site, including:

Turtles
Sharks
Lungfish
Dinosaur footprints

These discoveries collectively paint a vivid picture of the Cretaceous landscape and the creatures that inhabited it.

Importance of Preservation

The preservation of fossil sites like the one in North Arlington is crucial for paleontological research and our understanding of Earth’s history. By protecting these sites, we ensure that future generations can continue to explore and learn from the remnants of the past.
