What was the major geologic event during the Jurassic time period?
The breakup of the supercontinent Pangaea and the opening of the Atlantic Ocean was the major geologic event during the Jurassic time period. This led to significant changes in global climate and ocean circulation, as well as the evolution and diversification of marine and terrestrial life forms.
What were the dominant plant form during the Paleozoic Era?
During the Paleozoic Era, dominant plant forms included ferns, horsetails, and early seed plants like conifers and cycads. These plants were the main producers in terrestrial ecosystems, contributing to the diversity and abundance of life during this time period.
What was the first flowering plant?
The first flowering plant, also known as angiosperm, appeared during the early Cretaceous period, around 130 million years ago. This plant evolved from gymnosperms and quickly diversified to become the dominant form of plant life on Earth.
Which plant develops tubers during one of the stage of its life cycle?
The potato plant develops tubers during its life cycle. The tubers serve as a storage organ for nutrients and are the part of the plant that is used for propagation.
What major event in Earth's history began about 225 million years ago?
The major event that began about 225 million years ago was the Triassic-Jurassic extinction event, which marked the end of the Triassic Period and the start of the Jurassic Period. This event led to the extinction of approximately 50% of marine life species and set the stage for the dominance of dinosaurs in the Jurassic Period.
During what time period was the cryolosaurs in?
early life of antartica million of years ago
What period was the Jurassic period in?
you mean what era was the Jurassic period in it was in the mesezoic era inbeetween the triassic and the cretaceous periods mesezoic means middle life oh by the way anydinosaur from Jurassic park is not in the Jurassic don't believe they are there all from the cretaceous
What period was named after the jura mountains?
The Jurassic Period was named after the Jura Mountains, which are located in Europe. This period lasted from approximately 201.3 to 145 million years ago and is known for the dominance of dinosaurs and the diversification of marine life.
What period did life move to land?
The period during which life began to move on land was the Ordovician Period. It was during this time that evidence of plant spores from living fossils were found on land.
What was the major geologic event during the Jurassic time period?
The breakup of the supercontinent Pangaea and the opening of the Atlantic Ocean was the major geologic event during the Jurassic time period. This led to significant changes in global climate and ocean circulation, as well as the evolution and diversification of marine and terrestrial life forms.
What were facts about the Jurassic time period?
The Jurassic period lasted from about 201 to 145 million years ago. It was known for the dominance of dinosaurs, including iconic ones like the Stegosaurus, Brachiosaurus, and Allosaurus. This period also saw the evolution of early birds and the diversification of plant life, including the emergence of flowering plants.
What was the geography of the jurassic?
The Jurassic period witnessed the breakup of the Pangaean supercontinent into Gondwana and Laurasia. There was also the formation of intra-continental lakes and rivers that opened new evolutionary niches for marine and terrestrial life.
How much water covered the Earth during the Jurassic Period?
During the Jurassic Period, approximately 70% of the Earth's surface was covered by water. This extensive coverage of water allowed for the development of diverse marine ecosystems, including the proliferation of marine reptiles such as ichthyosaurs and plesiosaurs. The presence of shallow seas and extensive coastlines also provided habitats for a variety of marine life forms to thrive and evolve during this period.
What was plant life like back in the cretaceous period?
there were angiospems
When did plant life begin?
It began around the Precambrian period.
What plant and animal life is there in this time period?
lion rose
In the Pennsylvanian period what was the most common life?
In the Upper Carboniferous (Pennsylvanian) Period we have extensive evidence for plant life on land (the coal measures), it was also a period when giant insects were to be found and the period during which the reptiles began their evolutionary rise.Remember however that not all organisms leave fossils behind and we can therefore never say what the most common life was, just what life left most traces behind.
