DINOSAURS WORLD - EVERYTHING ABOUT DINOSAURS

On the Trail of Dinosaurs

Did you know that the first Tyrannosaurus Rex was found in Montana? Indeed, Montana is home to some of the world's best dinosaur dig sites. It is the perfect place for palaeontologists of all ages to explore the world's past and discover the secrets of ancient life from the Jurassic and Cretaceous periods.

Montana is proud of its geological heritage and has put together an official route called the Montana Dinosaur Trail (brochure and map available from Travel Montana upon request). As you travel across the northern prairies of Montana you will have the opportunity to stop at 14 different geological dig sites and museums.

To begin your journey it is wise to start at the Museum of the Rockies in Bozeman. This museum is home to one of the largest collections of dinosaur fossils in the world. The Seibel Dinosaur Complex contains some of the world's rarest fossils including one of the first skeletons identified to be a female dinosaur.

Tyrannosaurus Rex

From Bozeman you will need to travel north to the Old Trail Museum in Choteau. This site is famous for the discovery of the Maiasaurus. The specimen, found in 1989, is being restored. Other exhibits display the rich cultural history of the region. The Old Trail Museum is seasonal, so be sure to check whether it is open before planning your itinerary.

Just north of Choteau, in Bynum, is the Two Medicine Dinosaur Center. This interactive center offers several hands-on programs, from a simple 3-hour introduction to fossils, to a 7-day credit course that allows you to actually participate in a dig. The programs require advanced registration, so be sure to phone ahead. If you don't have time to join one of the programs there is still plenty to enjoy, including a Seismosaurus skeleton that is in the Guinness Book of World Records as the longest dinosaur skeleton on display.

Now your journey takes you east to Rudyard where you will want to stop at the Rudyard Depot Museum. Here you will have the opportunity to witness a life-sized duckbilled dinosaur and her nest. Other permanent and changing exhibits are sure to keep dinosaur enthusiasts enthralled.

Continue east on Route 2 and you will soon reach Havre and the H. Earl Clarke Memorial Museum. Here you will learn more about the duckbilled dinosaurs and discover fossilized dinosaur embryos. Another exhibit of interest is the Wahkpa Chu'gn Buffalo Jump Site, an archaeological treasure located just north of the museum.

Further east lies the Blaine County Museum in Chinook. Dinosaur exhibits in this museum include the Hadrosaur, Gorgosaurus, and Ankylosaurus. They also display several marine reptiles. A favorite exhibit for young visitors is the Look, Touch, and Wonder Room, where guests can handle a variety of fossils of plants and animals that once lived in the area.

Malta is home to two interesting dinosaur museums. The Great Plains Dinosaur Museum and Field Station has a fossil preparation lab where visitors can learn how fossils are cleaned and mounted for display. It also holds "Leonardo", a mummified dinosaur that is recognized as the world's best preserved dinosaur by the Guinness Book of World Records. The Phillips County Museum, also located in Malta, has many other interesting dinosaur displays including a Brachylophosaurus, a T-Rex skull, and an Albertasaurus.

From Malta you will travel east to Fort Peck, home of the Fort Peck Field Station of Palaeontology, and the Fort Peck Interpretive Center and Museum. The interpretive center holds one of the most complete T-Rex skeletons found to date and has a massive full-scale replica of "Peck's Rex" on display. At the nearby field station you can learn how displays such as the one at the interpretive center are made.

A bit out of the way by road, yet located directly south of Fort Peck, is the Garfield County Museum, located in Jordan. This is where the very first T-Rex fossils were found way back in 1902. In June and July, take some extra time to participate in the Paleoworld Research Foundation's public dig.

Continuing east you will eventually reach Glendive and the Makoshika State Park. The Lakotan word for "badland", Makoshika is part of the late Cretaceous Hell Creek Formation. Over ten different types of dinosaurs have been discovered in the area. The Makoshika Dinosaur Museum displays dinosaur fossils from around the world and includes many realistic replicas of what dinosaurs may have looked like when alive.

The final stop on your journey lies to the south at the Carter County Museum in Ekalaka. This museum includes a rare Anatotitan copei skeleton, a complete Triceratops skull, and many other unusual finds.

Be aware that many of these locations are seasonal, so you should plan ahead and confirm if they will be open during your trip. Many also have programs that offer hands-on experiences that require pre-registration.

Whether you are a young dinosaur enthusiast, or you have professional experience in the fields, Montana is one of the most desirable dinosaur destinations in the world. Be sure to allow plenty of time to enjoy the sights along the way, and have an excellent paleontological adventure! ( Lydia Kelly )

Fossils - Window Into Our Past

Fossils, the remnants or traces of ancient life, are like time capsules that offer glimpses into Earth's distant past. They provide invaluable clues about the history of life, the climate, and the geological processes that have shaped our planet.

Types of Fossils

Fossils come in various forms, each providing unique insights into the past:

Body Fossils: These are the actual remains of organisms, such as bones, teeth, shells, or entire bodies. They can be preserved in different ways:
- Permineralization: Minerals replace the original organic material, creating a rock-like fossil.
- Molds and Casts: Molds form when the original organism decays, leaving an impression in the surrounding rock. Casts form when minerals fill the mold, creating a replica of the organism.
- Carbonization: Organic matter is compressed and heated, leaving behind a thin film of carbon.
Trace Fossils: These are indirect evidence of life, such as footprints, burrows, or coprolites (fossilized feces). They provide information about the behavior and activities of ancient organisms.

The Fossil Record

The fossil record is a collection of fossils that have been discovered and studied. It is an incomplete record, as not all organisms fossilize and not all fossils have been discovered. However, it provides a valuable framework for understanding the history of life on Earth.

The Process of Fossilization

Fossilization is a complex process that requires specific conditions. Typically, an organism must be buried quickly after death to prevent decay. The organism is then subjected to various geological processes, such as sedimentation, pressure, and chemical reactions, which can lead to fossilization.

The Importance of Fossils

Fossils play a crucial role in several scientific fields:

Paleontology: Paleontologists study fossils to understand the evolution of life, the distribution of ancient organisms, and the history of Earth's ecosystems.
Geology: Geologists use fossils to date rocks, reconstruct ancient environments, and study plate tectonics.
Climate Science: Fossils can provide information about past climates, including temperature, precipitation, and atmospheric composition.

Famous Fossil Discoveries

Throughout history, numerous fossil discoveries have revolutionized our understanding of the past. Some of the most famous fossil finds include:

Archaeopteryx: A transitional fossil that bridges the gap between dinosaurs and birds.
Lucy: A nearly complete skeleton of an early human ancestor, providing insights into human evolution.
Tiktaalik: A fish with limb-like fins, representing a key step in the transition from water to land.

The Future of Paleontology

As technology advances, so too do the techniques used to study fossils. New methods, such as CT scanning and genetic analysis, are allowing scientists to extract more information from fossils than ever before. These advancements are opening up new possibilities for understanding the history of life on Earth.

By studying fossils, we can gain a deeper appreciation for the diversity of life, the interconnectedness of ecosystems, and the delicate balance of nature. As we continue to explore the fossil record, we may uncover even more astonishing discoveries that will reshape our understanding of the past and inspire future generations.

The Dinosaur That Never Went Extinct

When we think of dinosaurs, images of towering reptiles like Tyrannosaurus rex and Triceratops often come to mind. However, one group of dinosaurs managed to survive the mass extinction event that wiped out their non-avian relatives: birds.

A Feathered Lineage

The evolutionary link between dinosaurs and birds has been a subject of intense scientific study for decades. Fossil discoveries have revealed that many dinosaur species possessed feathers, a characteristic once thought to be unique to birds. These feathered dinosaurs, such as Archaeopteryx and Velociraptor, provide compelling evidence for the avian ancestry of dinosaurs.

Key features that link dinosaurs and birds include:

Feathers: Both dinosaurs and birds possess feathers, which are modified scales. Feathers serve various functions, including insulation, flight, and display.
Hollow Bones: Both groups have hollow bones, which reduce weight and improve their ability to fly or run.
Wishbone: The wishbone, or furcula, is a fused clavicle found in both birds and many dinosaur species. It provides structural support for the flight muscles.
Air Sac System: Both birds and some dinosaurs had an air sac system, which aids in respiration and helps to reduce body weight.

The Rise of Modern Birds

Following the Cretaceous-Paleogene extinction event, birds underwent a period of rapid diversification. They adapted to a wide range of ecological niches, from soaring through the skies to wading in wetlands. Modern birds exhibit a stunning array of adaptations, including specialized beaks, wings, and feet.

The Diversity of Birds

Birds are one of the most diverse groups of vertebrates, with over 10,000 species. They can be found in almost every habitat on Earth, from the Arctic tundra to the tropical rainforest. Some of the key adaptations that have contributed to their success include:

Flight: The ability to fly has allowed birds to colonize diverse habitats and escape predators.
Feathers: Feathers provide insulation, camouflage, and display. They also play a crucial role in flight.
Efficient Respiratory System: Birds have a unique respiratory system that allows them to extract oxygen from the air very efficiently.
Hollow Bones: Hollow bones reduce the weight of birds, making flight possible.
High Metabolic Rate: Birds have a high metabolic rate, which allows them to maintain a constant body temperature and generate the energy needed for flight.

The Future of Avian Research

As scientists continue to study the fossil record and the genetics of modern birds, we can expect to learn even more about the evolutionary history of these fascinating creatures. Ongoing research may reveal new insights into the origins of flight, the diversity of bird species, and the impact of human activities on bird populations.

By understanding the evolutionary history of birds, we can appreciate the incredible diversity of life on Earth and the delicate balance of ecosystems.

Birds are the living legacy of the dinosaurs. Their ability to adapt and evolve has allowed them

to thrive in a changing world. By studying the anatomy, behavior, and ecology of birds, we

can gain a deeper understanding of the past and a greater appreciation for the natural

world.
