Durham Dinosaur Trail: A Journey Through Time

The History of the Dinosaur Trail

In 1967, the Museum of Life and Science in Durham, North Carolina opened its Pre-History Trail, a beloved attraction that took visitors on a journey through 300 million years of Earth’s history. The trail featured dozens of dinosaur sculptures, each representing a different species that roamed the planet during the Mesozoic Era.

However, in 1996, Hurricane Fran caused extensive damage to the trail, forcing it to close. The dinosaurs were in need of repairs, and scientific research conducted since the trail opened had rendered many of them outdated.

The Reopening of the Dinosaur Trail

On July 25, 2009, the museum reopened the Dinosaur Trail with a new collection of scientifically up-to-date dinosaurs. The drab, tail-dragging sculptures of the past have been replaced by dynamic, brightly-colored works of paleo-art.

The new dinosaurs are more accurate representations of the animals they depict, based on the latest scientific research. Visitors can now see dinosaurs such as the feathered Archaeopteryx, the massive Triceratops, and the long-necked Brachiosaurus.

Highlights of the Dinosaur Trail

One of the highlights of the Dinosaur Trail is the “Brontosaurus,” a beloved sculpture that had its head removed in an act of vandalism. The head has since been reattached, and the dinosaur now stands proudly alongside its updated relatives.

Another highlight is the “Allosaurus vs. Stegosaurus” diorama, which depicts a dramatic battle between two of the most famous dinosaurs of the Jurassic Period. The diorama is a popular photo spot for visitors.

Educational Value of the Dinosaur Trail

The Durham Dinosaur Trail is not only a fun and exciting attraction, but it is also an educational experience. Visitors can learn about the different types of dinosaurs that lived during the Mesozoic Era, as well as the latest scientific research on these ancient creatures.

Mill Canyon Dinosaur Tracksite Damaged by Construction

Paleontological Significance of Mill Canyon

Mill Canyon Dinosaur Tracksite, located near Moab, Utah, is a significant paleontological site containing over 200 preserved dinosaur footprints dating back 112 million years. These footprints, known as ichnotaxa, provide valuable insights into the diverse life that inhabited the region during the early Cretaceous era. The site is particularly notable for its high species diversity, making it one of the most important track sites in North America.

Damage to Dinosaur Tracks

In January 2022, reports emerged that construction equipment had damaged a portion of the dinosaur footprints at Mill Canyon. The damage was discovered by local residents and paleontologists, who expressed shock and concern. According to Utah state paleontologist Jim Kirkland, approximately 20 to 30 percent of the tracks may have been impacted.

Cause of Damage and Responsibility

The damage was reportedly caused by heavy equipment used in the construction of a new elevated concrete boardwalk intended to replace the existing wooden walkway. The Bureau of Land Management (BLM), which manages the site, approved the construction project in 2021 and stated that any risk to the tracks would be mitigated through flagging and inspections during construction.

However, local experts and paleontologists criticized the BLM for not adequately consulting with them prior to the construction. They argue that the lack of a staff paleontologist at the Moab field office contributed to the oversight and potential damage.

Public Outcry and Legal Action

The damage to Mill Canyon dinosaur tracksite sparked public outcry and led to legal action. The Center for Biological Diversity filed a cease-and-desist letter demanding that the BLM halt construction in the area.

Weather and Erosion as a Factor

Recent weather and erosion may have also contributed to the damage. According to Lee Shenton, president of the Moab chapter of Utah Friends of Paleontology, heavy rain and sandstorms partially concealed the tracks, making them difficult to see. The construction crew may have inadvertently driven over the tracks, unaware of their presence.

Importance of Paleontological Oversight

The damage to Mill Canyon highlights the importance of paleontological oversight during construction projects in areas with known fossil resources. Paleontologists can identify fragile areas, recommend mitigation measures, and monitor construction activities to minimize the risk of damage to paleontological resources.

Ongoing Investigation and Mitigation

The BLM is currently investigating the extent of the damage and implementing mitigation measures to protect the remaining tracks. The agency has stated that it is committed to preserving the paleontological resources at Mill Canyon and will work with paleontologists to ensure the site’s long-term protection.

Unique Value of Mill Canyon Tracksite

Mill Canyon Dinosaur Tracksite is a unique and irreplaceable paleontological resource. The footprints provide a glimpse into the ancient world and offer valuable insights into the evolution and diversity of life on Earth.

Newly Discovered Tyrannosaur Stalked Ancient New Mexico

In the vast and ancient landscapes of New Mexico, a formidable predator once roamed, its name echoing the power and terror it commanded: Dynamoterror dynastes, the “powerful terror ruler.” This newly discovered tyrannosaur, a close relative of the iconic Tyrannosaurus rex, has shed new light on the diverse and dynamic world of these fearsome carnivores.

A Giant Among Giants

Dynamoterror was a colossal beast, stretching approximately 30 feet in length. Its massive frame dwarfed the early tyrannosaurs but fell just shy of the celebrity status of T. rex. Despite its slightly smaller size, Dynamoterror was undoubtedly a top predator in its ancient realm.

A Time of Evolutionary Turmoil

The Late Cretaceous period, when Dynamoterror roamed the Earth, was a time of rapid and dramatic evolutionary change for dinosaurs. North America was split in two by the Western Interior Seaway, creating two distinct subcontinents: Laramidia to the west and Appalachia to the east.

A Rich and Diverse Dinosaur Community

The southern regions of Laramidia, where Dynamoterror lived, were home to a diverse array of dinosaurs. Shovel-beaked hadrosaurs, heavily armored ankylosaurs, and horned ceratopsians were just a few of the neighbors Dynamoterror shared its habitat with.

Uncovering the Tyrant’s Secrets

The remains of Dynamoterror were discovered in New Mexico’s Menefee Formation in 2012 by a team of paleontologists led by Andrew McDonald of the Western Science Center and Douglas Wolfe of the Zuni Dinosaur Institute for Geosciences. The initial find consisted of fragmented bones spilling out of sandstone, hinting at something extraordinary.

Piecing Together the Puzzle

Over the years, researchers painstakingly assembled the scattered bone fragments, including two telltale skull bones called frontals. These critical pieces finally revealed the fossil’s true identity: a previously unknown tyrannosaur species. The discovery was published in the scientific journal PeerJ.

A New Branch on the Tyrannosaur Family Tree

Dynamoterror belongs to a specific subgroup of tyrannosaurs that includes some of the last and largest members of the family, such as T. rex. Its existence suggests that these derived tyrannosaurs emerged earlier than previously believed.

A Window into an Ancient Ecosystem

The presence of Dynamoterror in southern Laramidia provides further evidence that the dinosaur communities in the north and south of the Western Interior Seaway were distinct. This discovery supports the theory that dinosaurs underwent a rapid diversification during the Late Cretaceous period.

A Puzzle with Missing Pieces

The fossil record of dinosaurs from the 80-million-year-old rocks of southern Laramidia is relatively sparse, making the discovery of Dynamoterror particularly valuable. It hints at the existence of many more unknown dinosaurs that once roamed these ancient landscapes.

The Search Continues

The discovery of Dynamoterror has reignited the search for additional tyrannosaurs and other dinosaurs in the northern regions of Laramidia. Paleontologists speculate that there may be other unusual tyrant lizards yet to be unearthed, waiting to shed further light on the rise and dominance of these formidable predators.

Aaron O’Dea: Uncovering the Hidden History of Mass Extinctions

Paleontology in Panama: A Window into the Past

Paleobiologist Aaron O’Dea has made a name for himself by focusing on the seemingly insignificant. By studying the tiny fossils of marine creatures in Panama, he has uncovered surprising insights into the causes and consequences of mass extinctions.

For millions of years, North and South America were separated by a seaway. When the Isthmus of Panama formed, it isolated the Caribbean Sea, creating a unique environment that played a crucial role in the evolution of marine life.

O’Dea’s research has revealed that the Caribbean Sea did not experience a mass extinction immediately after the Isthmus of Panama rose out of the sea. Instead, there was a delay of two million years, challenging the traditional view of mass extinctions as sudden events.

The Importance of Non-Glamorous Specimens

Traditionally, paleontologists have focused on studying well-preserved fossils, such as dinosaur bones and teeth. However, O’Dea believes that these specimens are not representative of the vast majority of life that existed in the past.

He argues that more common and less conspicuous fossils, such as Bryozoa, can provide valuable insights into past environmental conditions. By studying the size and shape of fossilized Bryozoa, O’Dea can infer changes in water temperature over time.

Bryozoa: Indicators of Environmental Change

Bryozoa are tiny, colonial animals that resemble corals. They are sensitive to environmental changes, making them valuable indicators of past conditions. O’Dea’s research has shown that Bryozoa populations in the Caribbean declined significantly after the formation of the Isthmus of Panama, suggesting that the environmental changes caused by the isolation of the Caribbean Sea had a profound impact on marine life.

Ecological Changes and Mass Extinctions

O’Dea’s work emphasizes the importance of understanding the ecological changes that precede mass extinctions. By studying the gradual decline of Bryozoa populations in the Caribbean, he has provided evidence that environmental changes can trigger mass extinctions over a longer period of time than previously thought.

The Dual Nature of Aaron O’Dea’s Work

O’Dea is not only a scientist but also an accomplished photographer. He has found a way to combine his passions for art and science, creating stunning images of fossils and the people of Panama.

His photographs have been exhibited in museums and galleries around the world, showcasing the beauty and diversity of the natural world.

Challenges and Rewards of Paleontology in Panama

Paleontology in Panama is not without its challenges. O’Dea has faced illnesses, accidents, and the frustration of working with incomplete fossil records. However, he remains dedicated to his research, driven by the desire to uncover the secrets of the past.

The Significance of O’Dea’s Discoveries

O’Dea’s research has important implications for understanding the causes and consequences of mass extinctions. His work challenges the traditional view that mass extinctions are always sudden and catastrophic events.

By studying the gradual decline of Bryozoa populations in the Caribbean, O’Dea has shown that environmental changes can trigger mass extinctions over a longer period of time. This has important implications for understanding the potential impacts of climate change on modern ecosystems.
