This week we finally make it to the next time in the History of the Earth series! During the Ordovician the life on Earth continues to to radiate out into many strange new forms. the Radiodonts that once ruled take on a new role, our ancestors start to gain better defences and several new predators appear and begin to shape what life will look like for many millions of years going forward. We are still a long way from the present day but every step we take forward shows us a world slightly more familiar than before!

In the middle of the Cambrian, life on land was about to get a little more crowded. And those newcomers would end up changing the world. The arrival of plants on land would make the world colder, drain much of the oxygen out of the oceans and eventually, it would help cause a massive extinction event.

The Ordovician Period (That We Know Of)
MERCH!!! https://lindsaynikole.myshopify.com/collections/all
The Ordovician Period is one of the strangest and most influential periods in Earth's history, that we know of. Living in the shadows of the infamous Cambrian, the Ordovician period is often forgotten in terms of diversity, weirdness, and ultimate mass extinction. Today, I'll be giving you a rundown of this time, the animals that called it home, and the catastrophic way it ended.
A massive thanks to Gian for the phenomenal editing!

Titans of the Prehistoric Seas: The Lost Era of Ordovician Giant Shellfish Earth History Documentary
🌍 Have you ever imagined what life was like on Earth millions of years ago? Do you know how different the planet, the oceans and the creatures that lived there were from what we know today? To give you a glimpse of this distant period, today we're going to explore the Ordovician era. This is a fascinating and mysterious period in the planet's history, which has only recently begun to reveal some of its previously deeply buried secrets.
🔥 As a reminder, videos are published on SUNDAYS at 6.00 pm.

The Complete History Of The Earth: Ordovician Era
The Ordovician Period is intertwined with the Cambrian Period in terms of name. The name of this geologic age was inspired by a Welsh tribe known as the Ordovices. The Ordovician System completed the three-part classification of early Paleozoic rocks (Cambrian, Ordovician, and Silurian), all of which are named after Welsh tribes. Recognizing the Ordovician as a time gap between the Cambrian and Silurian put an end to a 40-year debate, removed an "overlapping system," and created a new time interval in its own right. This video talks about several important aspects of the Era.

What Was Life Like During the Ordovician Period?
The Ordovician period lasted about 45 million years and saw the transition from very primitive to relatively modern life-forms in the seas. The “Ordovician radiation” which followed the late Cambrian extinctions, lead to a tripling of marine diversity, the greatest increase in the history of life, and giving the highest levels of diversity seen during the Paleozoic Era.

The Hidden Secrets of the Ordovician Age
The origins of advanced forms of life began 500 million years ago during the Ordovician period ending with the Silurian extinction event. Australian biologist Richard Smith travels across the continent to study the fossil record of living things that continued to flourish at this time as it did in the earlier Cambrian period. Invertebrates, namely mollusks and arthropods, dominated the oceans and fish, the world's first true vertebrates, continued to evolve, with jaws appearing late in the period, not yet to diversifying onto land. About 100 times as many meteorites struck the Earth during the Ordovician compared with today.

🌍 Have you ever imagined what life was like on Earth millions of years ago? Do you know how different the planet, the oceans and the creatures that lived there were from what we know today? To give you a glimpse of this distant period, today we're going to explore the Ordovician era. This is a fascinating and mysterious period in the planet's history, which has only recently begun to reveal some of its previously deeply buried secrets.
🔥 As a reminder, videos are published on SUNDAYS at 6.00 pm.
-------------------------
💥 Ordovician:
- Brachiopods were extremely abundant during this phase of evolution still largely dominated by invertebrates. Brachiopods are animals with shells whose soft parts are contained between two valves. Although they resemble bivalves like clams, the body parts inside the shell are very different. What's more, their valves have a different symmetry to that of clams. A pedicle emerges from the larger of the two valves, enabling this brachiopod to attach itself to the seabed. Brachiopods are protostomans, one of two existing groups of bilaterians, along with Bryozoans. Bryozoans are mossy animals that live in colonies. They take a variety of forms, including arborescence or lace fan. Although they strangely resemble corals, they are not corals.
Each individual secretes an arborescent calcium carbonate skeleton attached to a hard surface. Each specimen, called a zooid, usually measures less than 1 millimetre in length and lives in its own little lodge. All interconnected, they form colonies containing millions of zooids, which can grow to several meters in size. Within the same colony, each individual plays a distinct role. Some gather food, others help to strengthen the group. Finally, some of these individuals contribute to cleaning. To feed, bryozoans create a water current that brings tiny creatures to their mouths. Most of the time, these are plant-like organisms such as phytoplankton. Bryozoans gradually colonize certain areas of the seabed, eventually building up into extensive reefs.
Trilobites make up a large part of the Ordovician fauna. These crustaceans, which secreted an easily identifiable segmented exoskeleton, reached their peak during the Ordovician. In fact, they are the most famous prehistoric animals after the dinosaurs. Over 18,000 species have been recorded. They ranged in size from 1 to 70 cm in length, and their way of life covered the whole range of Thalassic environments. Some were detritus feeders, grazers or even predators. While a few species mastered swimming, the majority of trilobites moved along the seabed, burrowing into the sediment to escape predators. Trilobites also developed the first advanced visual system. All trilobites had a head, called the cephalon, a thorax and a tail, as well as pairs of biramed legs on the ventral side. As with crustaceans, these legs had two branches, one serving as a gill for respiration, the other for locomotion and feeding. The most common trilobites include Cryptolithus, which measured around 1.5 cm in length, and Acidaspis, nearly 2 cm. But there were also specimens of far more spectacular dimensions. These included the Calymene, between 2 and 5 cm long, and above all, the Isoletus, which could commonly reach up to 38 cm in length. However, the world's largest trilobite species ever discovered is Isoletus rex. Its complete fossil measures no less than 72 cm long and 40 cm wide.

The origins of advanced forms of life began 500 million years ago during the Ordovician period ending with the Silurian extinction event. Australian biologist Richard Smith travels across the continent to study the fossil record of living things that continued to flourish at this time as it did in the earlier Cambrian period. Invertebrates, namely mollusks and arthropods, dominated the oceans and fish, the world's first true vertebrates, continued to evolve, with jaws appearing late in the period, not yet to diversifying onto land. About 100 times as many meteorites struck the Earth during the Ordovician compared with today.
