Fossilised Dinosaur Bone Fragment
Curious Minds Did You Know? Fossilisation is very rare! The organism needs to be covered by sediment very soon after it dies to preserve its remains.
This item is a real dinosaur bone fragment dated back to the Cretaceous period and was discovered in the USA. It comes in various sizes between 25 – 35 mm making each fossil unique and a perfect addition to your collection.
The prehistoric reptiles known as Dinosaurs became present during the Middle to Late Triassic Period of the Mesozoic Era, around 230 million years ago. They were members of a subclass of reptiles called the Archosaurs, meaning “Ruling Reptiles”, which is a group that also includes birds and crocodiles!
Unfortunately, Dinosaurs became extinct at the end of the Cretaceous Period, around 65 million years ago. The cause of the mass extinction that wiped these creatures out & marks the end of the Cretaceous and the beginning of the Paleogene period, remains a scientific mystery!
Scientists tend to be locked on to one of two hypotheses that may explain the catastrophic natural disaster that created this extinction, either an extreme asteroid or comet impacting with the Earth, or a massive bout of super volcano eruptions! Either scenario would have caused mass destruction to our planet, creating devastating havoc such as choking ash clouds & debris filling the skies, greenhouse gases locking in the atmosphere causing the temperature to soar to unbelievable highs, and much more! The world would have drastically changed for the worst, resulting in chaos for all that roamed the land! However, this disaster that's believed to have wiped out the dinosaurs remarkably didn't destroy everything! Most mammals, turtles, crocodiles, salamanders, and frogs somehow survived, as did birds, snails, bivalves, starfish, and sea urchins. Even hardy plants were able to escape death from the extreme climate changes!
Fortunately for us though, the extinct creatures are not a lost memory of what once was, as the discovery of their fossilised remains, such as bone, teeth & eggshell, can tell us so much information about an incredibly important part of history & help piece together the start of our very own existence!
