Unveiling the Seventh level: A Cretaceous Deep Dive
The Cretaceous period, a time synonymous with towering dinosaurs, held a world of wonders beneath the waves. Canadian paleontologists Dirley Cortésová and His Larson from McGill university uncovered a groundbreaking secret: a complex marine ecosystem teeming with creatures of colossal size and fearsome prowess. This ancient underwater world rivaled anything found in modern oceans in terms of biodiversity and complexity.
Their research focused on the Paja Formation, a treasure trove of ancient marine life dating back to the Lower Chalk period, roughly 130 to 113 million years ago. During this time, the Caribbean Sea was a warm, shallow expanse brimming with life. over millennia, the remains of this vibrant ecosystem were preserved in the seabed, eventually forming the Paja Formation, now located in central Colombia.
an Ocean of Giants
Most marine food chains today have a maximum of five or six levels, starting with primary producers like algae and culminating in apex predators like killer whales, sperm whales, or great white sharks. Though, Cortés and Larson’s findings challenge our understanding of these ancient food webs. They suggest the Paja ecosystem boasted a remarkable seventh level, a revelation that throws light on the evolution and diversity of life in ancient oceans.
“This is truly groundbreaking,” says Dr. Cortésová. “It expands our knowledge of the evolutionary history of marine life and suggests a level of complexity that we didn’t even consider possible.”
The Paja Formation is a window into a vanished world, providing invaluable insights into the forces that shaped life on Earth millions of years ago.

The Cretaceous period, a time ofen associated with towering dinosaurs, also witnessed an equally captivating world beneath the waves. Canadian paleontologists Dr. Dirley Cortésová and His Larson from mcgill University uncovered a surprising discovery: a complex marine ecosystem in the Paja Formation of Colombia, teeming with creatures of immense size and ferocity that rival anything found in modern oceans.
“The Paja Formation truly is a treasure trove for paleontologists!” Dr. cortésová exclaimed, describing the site as a snapshot of a thriving ecosystem from the Lower Chalk period, approximately 130 to 113 million years ago. “The Caribbean Sea at that time was warm, shallow, and brimming with life. The extraordinary preservation of fossils in the Paja Formation allows us to reconstruct the intricate food web that existed ther.”
Their groundbreaking research, published in the prestigious journal Zoological Journal of the Linnean Society, reveals a seventh level to this ancient marine food chain – a level previously unknown in paleontological history.
“These ‘monsters’ weren’t dinosaurs but massive, predatory marine reptiles known as pliosaurs,” Dr. Cortésová explained. One particularly noteworthy example is the Monquirasaurus boyacensis, which could grow up to ten meters long.
These apex predators dominated the ocean, preying on creatures that woudl have been considered the top of the food chain in our own time. According to Dr. Cortésová, “Understanding the arrangement of Mesozoic ecosystems helps us examine how ecosystems develop over time. We try to reveal the structure of ancient communities,which stood at the beginning of today’s biodiversity.”
The Paja Formation, with its rich and remarkably preserved marine ecosystem, provides a unique window into the distant past. It allows scientists to piece together the story of these prehistoric giants and understand how life evolved into the diverse forms we see today.
Unearthing Ancient Giants: A Glimpse into the Paja Ecosystem
The Paja Formation, a treasure trove of prehistoric secrets, has yielded another amazing discovery: a complex ecosystem teeming with life, unlike anything we’ve ever seen. While previous research highlighted marine reptiles and dinosaurs, recent excavations have uncovered evidence of a seven-tiered food chain, culminating in a group of colossal pliosaur predators.
These weren’t just massive sea creatures; we’re talking about monsters like Monquirasaurus (Kronosaurus) boyacensis, which could grow to a staggering ten meters in length. these apex predators ruled the waters, preying on creatures that would have been dominant in our oceans today. This stunning find challenges our existing understanding of prehistoric marine life and the intricate balance of ancient ecosystems.
illuminating Evolutionary Paths
“understanding how Mesozoic ecosystems were structured helps us piece together how ecosystems evolve over time,” explains Dr. cortésová. “By carefully studying ancient communities like the one in the Paja Formation, we gain invaluable insights into the forces that have shaped biodiversity over millions of years.”
Unveiling the Paja’s Secrets
Despite this remarkable discovery, the Paja ecosystem still holds many unanswered questions. “There’s so much more to learn,” Dr. Cortésová emphasizes. “We need to continue excavating the Paja Formation to uncover more fossils and piece together the lives of these incredible creatures. We also want to explore how climate change and other environmental factors might have influenced the evolution of these complex ecosystems.”
A Message for Future Generations
“Exploring the past allows us to better understand the present and prepare for the future,” Dr. Cortésová advises. “By studying ancient ecosystems, we gain a deeper appreciation for the delicate balance of life on Earth and the importance of protecting our planet’s biodiversity. “

An Interview with Dr. Dirley Cortésová
Archyde: Dr. Cortésová, your recent research on the Paja Formation has generated quite a buzz in the scientific community. Can you tell us more about this remarkable discovery?
Dr. Cortésová: Indeed, the Paja Formation truly is a treasure trove for paleontologists! It’s a snapshot of a thriving ecosystem from the Lower Chalk period, approximately 130 to 113 million years ago. The Caribbean Sea at that time was warm, shallow, and brimming with life. The extraordinary preservation of fossils in the paja Formation allows us to reconstruct the intricate food web that existed there.
Archyde: Your research suggests this ancient food web had a seventh level, a concept unprecedented in paleohistory. Tell us about this remarkable finding.
Dr. Cortésová: You’re right, it is indeed a groundbreaking discovery. We identified a group of massive, predatory marine reptiles known as pliosaurs that inhabited this ecosystem. One especially noteworthy example is the Monquirasaurus boyacensis, which could grow up to ten meters long. These apex predators dominated the ocean, preying on creatures that would have been considered the top of the food chain in our own time.
Archyde: What implications does the discovery of this seventh level have for our understanding of ancient ecosystems?
Dr. Cortésová: Understanding the arrangement of Mesozoic ecosystems helps us examine how ecosystems develop over time. We try to reveal the structure of ancient communities, which stood at the beginning of today’s biodiversity. Pliosaur dominance in the Paja ecosystem shows how unpredictable and dynamic these ancient worlds could be.
Archyde: What other secrets do you think lie hidden within the Paja Formation? What future research plans do you have?
Dr. Cortésová: There’s so much more to learn! We need to continue excavating the Paja Formation to uncover more fossils and piece together the lives of these unbelievable creatures. We also want to explore how climate change and other environmental factors might have influenced the evolution of these complex ecosystems.
