Dinosaur Fossil:

Dinosaur is perhaps one of the most amazing creatures that ruled over the planet for more than 160 million years. Ranging from the size of hummingbirds to the size of large trucks and buildings, these ferocious “lizards” once battled for dominance but went extinct because of a still unknown cause.

Dinosaurs have already gone extinct but much information about them still remain-because of their fossils. Fossils don’t easily degrade or decompose; hence they are a good source of evidence about the prehistoric life on the planet.

In some instances, these fossils tend to be preserved in the most bizarre ways and the most unusual locations.

Many paleontologists have been digging and discovering these dinosaur fossils from various geographical locations as earliest as 17th century till today. Excited to know them?

Dinosaur Fossil Discoveries

Here are the 15 most stunning and most remarkable dinosaur fossil discoveries ever found listed in a chronological order starting from the earliest.

1. Femur of A Megalosaurus (1676) – England

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (2)

In 1676, a portion of the femur of a very large organism was first discovered by an English professor at Oxford University. During that time, scientists couldn’t decide whether that fossil was from a reptile or other similar organism and still could not believe how large it was.

  • One hundred and fifty years later, scientist William Buckland finally classified this fossil under the genus name Megalosaurus.
  • In honor of William Buckland, this creature was assigned under the scientific name Megalosaurus bucklandii.
  • However, it took more than 20 years for a paleontologist named Richard Owen to exclusively identify the fossil as a dinosaur.

  • It was when then the 12-year-old Mary Anning noticed some weird stones found inside the abdomen of the ichthyosaur fossils she was collecting that she found out these were actually fecal matter!.
  • Beyond its bizarreness, these coprolites serve as tremendous fossils that help scientists to decipher what type of food extinct dinosaurs ate.
  • Specifically, in Australia, these coprolites revealed that plesiosaurs that lived during the Cretaceous period were bottom feeders.

3. The “Missing Link” (1860) – Germany

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (6)

In 1860, scientists were shocked to discover a fossil of from the limestone deposits of Solnhofen, Germany–a fossil that is known to be the transition (or missing link) between extinct dinosaurs and modern birds, the Archeopteryx.

  • For scientists, this organism had characteristics of both birds and dinosaurs. This organism is considered by many as the oldest known bird, assumed to lived during the Late Jurassic period.
  • The name “Archeopteryx” comes from the Greek words “archaios” and “pteryx” meaning “ancient” and “feather” respectively.
  • This discovery of the Archeopteryx has led to more discoveries of other transitional organisms; however, still, none have had the same remarkable impact as this organism.

4. Hadrosaurus (1868) – United States of America

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (8)

Named by Joseph Leidy, an American paleontologist, the Hadrosaurus is a species of duck-billed dinosaurs that lived in the forests and freshwaters of North America.

  • Historically speaking, this fossil excavated was considered as the first ever (nearly) complete dinosaur fossils in the United States and probably the complete one to be discovered anywhere in the world.
  • The first fossil of this dinosaur was discovered and scientifically documented in 1868.
  • During Leidy’s time, this dinosaur was thought to walk with tripodal (much like a kangaroo position); however, modern studies about this dinosaurs reveal that they walk in an upright position.

5. Diplodocus (1878) – United States of America

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (10)

Aside from being known as the longest dinosaur, the Diplodocus is also famous for its unique body construction, having two rows of bones under its tail for additional structural support.

  • Among all the fossils of Diplodocus unearthed, the species D. hallorum was longest with 33 meters long overall skeleton.
  • In 1878, the first skeleton of Diplodocus was discovered the at Como Bluff, Wyoming by scientists Benjamin Mudge and Samuel Wendell Williston.
  • The remains of this dinosaur species are very common, except for their skulls, which are often not found with the overall body skeleton.

6. Coelophysis (1881) – United States of America

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (12)

Most Coelophysis fossils were discovered in Rio Arriba County, New Mexico and most of these fossils were already 205 to 210 million years old.

  • Based on their fossilized stomachs containing small reptiles, fish, and other bones of Coelophysis, scientists concluded that this species was a carnivorous cannibal.
  • The name of this dinosaur came from the Greek words “koilos” and “physis” which mean “hollow” and “condition” respectively.
  • Although this fossil does not necessarily make a hit among paleontologists, its discovery revealed that flash floods usually drown most dinosaurs that travel and live in large groups.

7. An ongoing Combat Forever (1971) – Mongolia

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (14)

Another fantastic fossil discovery was the ‘ongoing fossilized combat‘ between a carnivorous Velociraptor and an herbivorous Protoceratops – direct evidence of how rampant predation among dinosaurs was during that time.

  • In the fossil, the Protoceratops was hit at its carotid artery by the Velociraptor’s claw. The Protoceratops fought back and locked its jaws on the arms of the Velociraptor’.
  • Scientists believe that while these dinosaurs were fighting for their lives, a large land mass (presumed to be a sand dune) suddenly collapsed on them.
  • This fossilized combat between the two dinosaurs was unearthed in Gobi desert, Mongolia in 1971.

8. Good Mother Lizard (1978) – United States of America

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (16)

Also known as the “Good Mother Lizard“, the Maiasaura is considered by many paleontologists as one of the most important dinosaur fossils to provide a detailed view of how those amazing creatures lived.

  • The fossils accurately revealed the growth rate, metabolism, sexual maturity, and physical maturity.
  • The fossils of the Maiasaura also serve as important evidence that dinosaurs once had an interactive family life. The fossils also show that they don’t usually abandon their young when hatched.
  • Fossils of this dinosaur were first excavated from a bone bed in western Montana in the early 1990s.

9. intact Plesiosaur Skeleton (1994) – North America

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (18)

Plesiosaurs are carnivorous dinosaurs that ruled the vast oceans and seas during the prehistoric period. In particular, one plesiosaur fossil of the species known as the Nichollsia Borealis was discovered in North America in 1994.

  • The fossil was still intact, and the whole body was completely preserved, making it one of the oldest and one of the complete fossil ever discovered.
  • This fossil was discovered in a 200 feet deep surface mine in Alberta.
  • This fossil now represents the amazing marine life in North American prehistory.

10. Another Plesiosaur Skeleton (2006) – Australia

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (20)

Another plesiosaur fossil that made to this list is the Umoonasaurus, an ancient sea reptile about the size of a sea lion.

  • This organism derived its name from “Umoona“, an Aboriginal name for the specific region in South Australia where almost all Umoonasaurus fossils were discovered.
  • Umoonasaurus fossils are spectacular due to their bright blue to the overall green skeleton.
  • The discovery of this dinosaur paved the way for scientists to conclude that adults of this species tend to return to the shallow inland waters to raise their young.
  • Scientists also found that they might have developed specific mechanisms to cope with the harsh environmental condition.

11. The “Monster” (2006) – Norway

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (22)

Another group of marine reptiles that ruled over the prehistoric period were the pliosaurs. In particular, a 33-foot fossil of a pliosaur dubbed as the Monster was discovered in Arctic island of Spitsbergen in Norway’s Svalbard archipelago.

  • This 150-year-old fossil was the largest and most complete pliosaur fossil ever discovered.
  • The unearthed fossil includes a skull measuring 2.1 meters, and enormous teeth that are the size of cucumbers.
  • Pliosaurs were typically short-necked and had sets of powerful flippers that help them propel themselves in water.

12. A Nest of 15 Baby Dinosaurs (2011) – Mongolia

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (24)

In 2011 in Mongolia, paleontologist David Fastovsky unearthed a nest containing the remains of 15 baby dinosaurs of the species Protoceratops andrewsi.

  • Fastovsky said that this nest might have been overrun by sand dunes during a storm, hence buried them all alive.
  • This discovery of the nest provides the first evidence that young dinosaurs of this species stay in nests for an extended period.
  • Chemical analyses revealed that all the 15 dinosaurs were relatively of the same size and at the same period of physical and sexual maturity; hence suggesting that they were infants that came from the same mother.

13. A Mother Dinosaur Giving Birth (2011) – China

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (26)

The next dinosaur fossils in our list are the 248-million-year-old fossil of a female ichthyosaur giving birth to three offspring, which was recently discovered in South Majiashan, China last 2011.

  • The fossil includes the mother dinosaur who is giving birth to (1) an offspring that is halfway out of the birth canal, (2) one already found outside, and the (3) one waiting to be born.
  • Despite this, ichthyosaurs were only discovered in 2012.
  • Reptiles are known to be egg-laying creatures, but the discovery of this ichthyosaur proves that somehow confuses the views of scientists about the evolution of live-bearing.

14. The Smallest Fossil (2011) – United Kingdom

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (28)

Just about the size of bread (40 centimeters), the “Ashdown Maniraptoran” fossil is now considered as the smallest dinosaur fossil ever found (yet).

  • Recently discovered in 2011 in the United Kingdom, this fossil rivals the Anchiornis genus, which was previously known as the smallest dinosaur.
  • At present, the skull of this fossil is yet to be found; hence, its type of diet is still unknown.
  • Although most non-avian taxa of this clade have gone extinct during the late Mesozoic, other Maniraptoran species, including birds and other closely related species still exist up until today.

15. Mosasaurus Fossil (2015) – Japan

15 BEST Dinosaur Fossil Discoveries Of All Times | Bio Explorer (30)

Last but not the least dinosaur fossil in this list belonged to the marine reptile named Mosasaurus. Before its discovery, scientists have long been digging up lakes and rivers in central and western Europe.

  • Previous fossils of the Mosasaurus have already been discovered along the East Coast of North America, the Pacific Coast of North America, Europe, and North Africa. However, this fossil found in Japan was the first to fill the gap between the Middle East and the Eastern Pacific.
  • The fossil was well-preserved; the analysis revealed that this creature had a binocular vision.
  • Interestingly, the skeleton of the Mesosaurus was the first ever fossil to be identified as extinct.
