Not too long ago, scientists unveiled a new species of monstersaur named Bolg amondol. This unexpected finding reflects the complicated evolutionary relationship among big lizards. Even more amazing was the fact that this rare discovery took place in Grand Staircase-Escalante National Monument, in Southern Utah, United States. Bolg amondol is roughly three feet long from tip of snout to tip of tail. About the size of a raccoon, it could grow larger since its tail and torso can be long.
Bolg amondol was only known from its original 2005 description. Its importance wasn’t appreciated until decades later by a lizard evolution expert. This revelation opens up new avenues for understanding the diversity and adaptation of large predatory lizards during the Late Cretaceous Period. The name Bolg amondol is a reference to the goblin prince in J.R.R. Tolkien’s “The Hobbit.” “Bolg,” with its hard consonant, can have a very negative connotation, whereas amondol, or “mound-headed,” derives from the beautiful Elvish language of Sindarin.
Distinctive Features of Bolg amondol
Bolg amondol is distinctive because of its remarkable physical traits. It has needle-like, spire-shaped teeth and distinct polygonal, pitted armor secured to its head. Combined, these incredibly ornate features complete a flamboyant look for the beast. Beyond their aesthetic appeal, they serve important biological functions, aiding in predator or competitor defense.
Similar to the Savannah monitor lizard, Bolg amondol exemplifies the diversity of large lizards that existed millions of years ago. Its unique morphology sheds important light on the adaptations that helped these monsters conquer the landscape. Researchers hypothesize that Bolg amondol’s size and armor protected it from the dangers of its predatory lifestyle. These adaptations made it a predatory powerhouse, helping it hunt in the sub-tropical floodplains of its environments.
Evolutionary Insights
The fossil record of Bolg amondol further bolsters our understanding of evolutionary relationships among large lizards. This new species is most closely related to a species that’s found in the Gobi Desert of Asia. These paleogeographic links serve to illustrate the general biogeographical trends across the whole of the Late Cretaceous Period. They suggest that big-bodied lizards were much more widespread than we previously thought.
Bolg amondol’s discovery, along with other fossils from the Kaiparowits Formation, indicates that at least three types of predatory lizards inhabited this region during the Late Cretaceous era. This discovery underscores Southern Utah as an important location for research into the prehistoric world. It also reveals a surprising variety among large lizards that flourished during the height of the dinosaur age.
Implications for Future Research
We hope that the recognition of Bolg amondol will encourage more research on large lizards and the macro evolutionary routes that they can take. Research scientists are currently conducting research on these fossils. With this research, they will be able to test a number of hypotheses to determine exactly where Bolg amondol fits on the lizard tree of life. If true, this study would radically change our picture of lizard evolution. It showcases the diversity of life that existed during a time of rapid ecological transformations on Earth.
