One remarkable fact about fossils is that parrots, which we typically associate with small sizes, used to be much larger in the past. In 2019, a fossil of a parrot that lived around 16 to 19 million years ago was discovered. The bird, affectionately called “Squawk Zilla,” was approximately three feet tall and weighed around 15 pounds. This finding surprised many, as the bones were initially misidentified as belonging to an eagle due to the assumption that parrots could not reach such large sizes.
To get a glimpse into the extensive collection of fossils, we take you to the Big Bone Room at the American Museum of Natural History. This room houses over a thousand fossil bones, with only a minuscule fraction on public display. About two-hundredths of a percent of the museum’s vertebrate fossils are available for public viewing, while the majority are stored in behind-the-scenes areas and utilized for research purposes by paleontologists worldwide.
Carl Melling, a senior museum specialist at the AMNH, shares the fascinating story behind one of his favorite specimens: the beak bone of a triceratops. This specific fossil provides valuable insights into how the beak of the triceratops was structured and supplied with blood during the animal’s lifetime. Fossils, in general, can be defined as the preserved remains, traces, or imprints of an organism. The common definition also requires that fossils be at least ten thousand years old.
Fossils can be found in various forms, including body fossils and trace fossils. Body fossils, such as bones and teeth, are what most people envision when thinking about fossils. Trace fossils, on the other hand, provide evidence of an animal’s behavior, such as footprints, nests, or even feces. These remnants of ancient life allow scientists to reconstruct prehistoric ecosystems and understand the behaviors and interactions of long-extinct animals.
The word “fossil” can be traced back to the Latin term “fascists,” which means “dug up.” In its earliest usage around the 1600s, “fossil” referred to anything that had been unearthed. Over time, it came to specifically denote the preserved remains of ancient organisms. Identifying the exact nature of a fossil can sometimes be challenging. Microfossils, for example, are fossils of bacteria, pollen, or other microscopic organisms that cannot be studied with the naked eye.
In 2017, paleobiologist J. William Schopf published a groundbreaking paper on microfossil microbes believed to be 3.4 to 3.6 billion years old. These microfossils provided possible evidence of some of the oldest life forms ever discovered. However, skeptics argued that the so-called fossils were merely minerals that resembled biological specimens. The debate surrounding the authenticity of these microfossils continues among scientists to this day.
Discovering and studying fossils is a process that requires patience and perseverance. For example, William Zinsmeister unearthed the fossil of an approximately 15-ton, 40-foot-long Alosaurs (a plesiosaur) in 1989 on Seymour Island in Antarctica. Excavating in the harsh Antarctic conditions was slow and limited to only a few weeks each year. It took nearly three decades to complete the excavation, highlighting the substantial time investment often required in paleontological endeavors.
The fascination with fossils is not a recent phenomenon. Humans have been discovering and utilizing fossils for various purposes throughout history. For example, ancient Greeks believed in the existence of Cyclopes, giant creatures with a single eye. Some speculate that these mythical beings may have been inspired by large elephant skulls found by ancient people. Mammoth bones and teeth have also been discovered throughout history, with some being mistakenly interpreted as the remains of giant humans.
It was not until the early 19th century that the true nature of fossils began to be understood. In 1824, paleontologist William Buckland correctly identified a fossil as belonging to a reptile, specifically a Megalosaurus. Another significant discovery took place a few decades later when an Archaeopteryx fossil was found. This fossil contained both feathers and teeth, providing evidence for the link between dinosaurs and birds.
In recent years, advancements in technology and scientific techniques have deepened our understanding of fossils. In 1996, the fossil of a non-avian dinosaur, Sinosauropteryx, was discovered, complete with preserved feathers. This finding shed light on the colorful appearance of certain dinosaurs, with experts believing that Sinosauropteryx had a red and white tail. The fossils of other dinosaurs, such as the Anchiornis, have also revealed detailed information about their coloration.
Paleontologists are constantly unearthing new evidence and revising our understanding of prehistoric life. In 2019, researchers working in the Hell Creek Formation in North Dakota found fossils of fish that perished during the event that wiped out 75% of the Earth’s plant and animal species, including dinosaurs. This finding provides further insights into the impact and aftermath of the catastrophic event that led to the extinction of the dinosaurs.
Trace fossils, such as footprints and coprolites (fossilized feces), offer unique glimpses into the behavior and diet of ancient organisms. They allow scientists to reconstruct the lives of long-extinct creatures. However, it is important to note that not all fossils are created equal. In some cases, fossilized resin or amber can preserve intricate details of ancient life. In 1990, scientists found a mosquito trapped in amber that had supposedly fed on dinosaur blood. However, this scenario is purely fictional, inspired by the plot of the movie Jurassic Park.
Fossil records also reveal surprising details about the diversity and evolution of different species. For example, some crocodile relatives were herbivores, and there was even a crocodilian species known as the “cat crocodile” due to its mammal-like characteristics. Additionally, the discovery of the 110 million-year-old dinosaur skeleton in Alberta, Canada, shed light on the bloat and float process, where dead animals bloat with gases, float through water, and eventually sink, becoming preserved in sediment.
Throughout history, there have been debates and controversies within the field of paleontology. The Bone Wars of the late 19th century saw paleontologists competing to name and identify numerous dinosaur species. Notably, the Apatosaurus and Brontosaurus were initially thought to be separate species until a study in 1903 concluded that they were, in fact, the same genus. However, a more recent study published in 2015 suggested that they should be considered distinct animals.
Lastly, we end with an astonishing fossil discovery: a prehistoric penguin known as the Crossvallia waiparensis. This ancient penguin, which lived between 56 and 66 million years ago, stood at an impressive height of 5 feet 3 inches, taller than the average human. However, even this penguin predecessor was overshadowed by an even larger species called the Palaeudyptes klekowskii, which could reach a towering height of 6 feet 5 inches.
Fossils continue to captivate the imaginations of scientists and enthusiasts alike, offering glimpses into the mysteries of our planet’s prehistoric past. These preserved remains, traces, and imprints allow us to uncover not only the physical characteristics of ancient organisms but also the fascinating behaviors, interactions, and diversity of life that once thrived on Earth. With ongoing research and new discoveries, our understanding of fossils and the stories they tell will undoubtedly continue to evolve.
