Fossils from one billion years old green seaweed were identified, Paleontologist Virginia Tech made a remarkable discovery in China: 1 billion green algae microalgae per year that can be attributed to the ancestors of the earliest land and tree plants that flourished 450 million years ago.
Microfossil algae, known as Proterocladus antiquus, are barely visible to the naked eye at a length of 2 millimeters or about the size of a typical flea.
They were printed on rocks from a dry, former ocean, near the city of Dalian in northern Liaoning province.
Previously, the most convincing fossil of green algae was found in a rock that is around 800 million years old.
This new fossil shows that green algae were a key player in the ocean long before their descendants moved from land plants and took control of the land. Fossils from one billion years old green seaweed were identified.
The entire biosphere is highly dependent on plants and algae for food and oxygen, but terrestrial plants did not develop around 450 million years ago.
Our study shows that green algae has developed at the latest after 1 billion years and the record of green algae has increased by around 200 million years.
Shuhai said the current hypothesis is that the earth developed trees, grasses, food plants, shrubs, and even kouzou from green algae, which are aquatic plants. Fossils from one billion years old green seaweed were identified.
Geologically, they came out of water millions and millions of years ago and adapt and develop on land, their new natural environment. These fossils are related to the ancestors of all modern land plants we see today.
However, Xiao added the warning that not all geologists were on the same page, that the debate about the origin of green plants remained controversial.
Not everyone agrees with us; Some scientists believe that green plants come from rivers and lakes and then conquer and land in the ocean, “added Xiao, a member of the Virginia Tech Center for Global Change. Fossils from one billion years old green seaweed were identified.
There are three main types of algae: chocolate (Phaeophyceae), green (Chlorophyta) and red (Rhodophyta), and thousands of all types.
Red seaweed fossils found on the seabed today date from 1.047 billion years ago.
There are several modern green algae that look very similar to fossils found, researchers say.
A group of modern green algae, known as siphono cells, are very similar in shape and size to fossils found.
Photosynthetic plants, of course, are very important for the ecological balance of the planet, because they produce carbon and organic oxygen through photosynthesis and provide food and protection for large numbers of mammals, fish, and more. Fossils from one billion years old green seaweed were identified.
Tang was the one who discovered a micro-algae fossil with an electron microscope on the Virginia Tech campus and told Xiao.
To make fossils more visible, mineral oil is dripped into fossils to create strong contrast.
This algae displays many branches, erect buds and special cells known as Akinets, which are very common in this type of fossil, according to researchers.
Together, these characteristics strongly indicate that the fossil is a green algae with a complex multicellularity that is around 1 billion years old. Fossils from one billion years old green seaweed were identified.
They probably represent the earliest fossil green algae. In short, our research shows that the ubiquitous greenery that we see today can be traced back to at least 1 billion years.
Millions of years later, sediment rises above the ocean and becomes a dry land where the fossils from Xiao and his team were extracted, which included scientists from the Nanjing Institute of Geology and Paleontology in China.
