Tehran – In a groundbreaking paleontological discovery, Iranian scientist Dr. Naslora Abbasi, a researcher at Zanjan University, unveiled the world’s first fossilized evidence of an ancient bird mating ritual.
This unprecedented discovery shed light on bird behavior from 130,000 to 15 million years ago, and marks a major milestone in the paleontology of behavior.
Unlike typical microfossils that retain isolated footprints, this exceptional site features over 70 exceptional trackways etched into sediment slabs, forming a complex tableau of ritualized bird displays.
These tracks record movements such as walking, high stepping, stomping, hopping, pecking, short flights, and lateral jumps.
“This discovery transcends bones and immortalizes behavior,” Abbasi said in an exclusive interview. “What’s here isn’t just an exercise, it’s a performance. A male Miocene bird proudly stomps on an ancient mud flat, stomps its feet, jumps up to the side, flaps its wings temporarily, and sticks it with precision.
Detailed morphometric analysis of the footprint shows that the bird weighs about 320 grams, has a hip height of about 6 centimeters, and is closely matched with modern feathers (Family Chrysanthemidae). The strong behavioral similarities led Abbasi and his team to coin a new etology class, especially in microfossils, to track fossils of mating rituals.
“This is the oldest direct evidence of complex courtship behavior ever recorded in birds,” stressed Dr. Abbasi. “This opens a new chapter to understand how social and reproductive behaviors, particularly social and reproductive behaviors, can act, so that behavior can be fossilized. Previously, such complex displays were thought to be nearly impossible to detect on a rock record.”
Discovery is the role of exemptions, a step forward in paleontology through the study of microfossils. When fossils once spoke primarily of anatomy, they now talk about social interaction, communication, and even courtship. The ability to read choreography of action on stones provides scientists with an entirely new lens for interpreting ancient life.
“The beauty of this site lies in its integrity,” explained Abbassi. “We don’t see a single footprint or a random set of steps, and we see the choreography of a species that has been preserved for millions of years – rituals, its rhythm, its intent, and more.
Beyond scientific importance, this discovery firmly places the red formations of Iran’s upper part on the global paleontological map of terrestrial territories. The rich layered deposits of the region, which have long been studied for sediment importance, now stand as an important archive of behavioral evolution.
“The findings examine the location of Iran at the forefront of urination research,” Abbasi said. “It shows that we don’t need to look to other continents to understand the evolution of early bird behavior. The record is located under our mountains, our rocks, our feet.”
Dr. Abbassi, a leading figure in exemptions and geology, holds a Ph.D. in geology specialised in paleontology from Shahid Beheshti University in Tehran. For the past decade he has spearheaded pioneering research into sedimentary structures and trace fossils across Iran. His work continues to redefine what is possible in the field of fossilized behavior.
“This is just the beginning,” he concluded. “If you can discover the mating dance preserved in stone, imagine what else awaits you. Other actions, other species, other stories. The Earth remembers more than we thought.”
In 2022, Abbasi wrote Miocene wildlife in Zanjan in northwestern Iran. This is a comprehensive volume published by Zanjan University. This book documents the region’s rich fossil heritage and serves as a fundamental reference for researchers studying the medieval medieval series/epoch ecosystem.
