Artistic reconstruction of Bolg amondol

An ancient creature discovered in North America is providing valuable insights into the ecosystem around 75 million years ago.
Described as resembling a goblin emerging from the rocks, the newly identified species belongs to a group of reptiles known as monstersaurs that lived during the Late Cretaceous Epoch. Measuring around 3 to 4 feet in length, the creature, named Bolg amondol, is believed to have been a formidable predator.
The unique fossil of B. amondol was initially unearthed in Utah by Joseph Sertich from the Smithsonian Tropical Research Institute. Thought to belong to a known prehistoric lizard, further examination revealed its classification as a monstersaur. The fossil also provided evidence of a defense mechanism where the creature could shed its tail when threatened, a trait observed in some modern-day lizards.
According to researchers, B. amondol likely preyed on small mammals, frogs, snakes, and insects, and may have even consumed dinosaur eggs. The prehistoric environment where it thrived was described as swampy, hot, and humid, resembling the modern-day US Gulf Coast.
Reflecting on the discovery, paleontologist Randall Nydam from Midwestern University emphasizes the importance of understanding the past ecosystems and the impact of environmental changes on ancient species. He notes the extinction of such creatures due to environmental shifts.
With the unveiling of B. amondol, experts hope to enhance the public’s perception of monstersaurs and envision a prehistoric landscape teeming with these fascinating and fearsome creatures.
