Which of the following fossil is the characteristic fossil of Upper Gondwana?
Glossopteris
Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana.
Which is an upper Gondwana Flora?
Upper Gondwana: This is characterised by the arrival of Ptilophyllum flora till the end of Gondwana era, ranging from Jurassic to Lower Cretaceous, in which Dubrajpur, Rajmahal, Kota, Jabalpur, Gangapur, Shivganga, Bhuj, Pariwar, etc., Formations are conveniently included.
Which came first Pangea or Gondwana?
According to plate tectonic evidence, Gondwana was assembled by continental collisions in the Late Precambrian (about 1 billion to 542 million years ago). Gondwana then collided with North America, Europe, and Siberia to form the supercontinent of Pangea.
Why are Gondwana fossils important?
The Indian Gondwana Flora: The most important fossil flora of India is what is known as the Gondwana Flora which covers the period Upper Carboniferous to Jurassic. This was followed in the Upper Carboniferous and the Permian by severe glaciation and the Permian in India is the greatest coal- forming age.
What is the importance of Gondwana?
The creation of Gondwana In this world, Gondwana conducted its slow grind to supercontinent status. Bits and pieces of the future supercontinent collided over millennia, bringing together what are now Africa, India, Madagascar, Australia and Antarctica.
Which country was not a part of Gondwanaland?
The correct answer is Europe. Europe was NOT a part of Gondwana Land.
How was India formed out of Gondwanaland?
It was one single landmass. Due to the impact of the convectional currents, the crust was split into many pieces. The Indo Australian plate got separated from the Gondwana land and drifted towards the north. As it drifted towards the north, it collided with the Eurasian Plate.
What do you know about the Gondwana land?
Gondwanaland or “Gondwana” is the name for the southern half of the Pangaean supercontinent that existed some 300 million years ago. Gondwanaland is composed of the major continental blocks of South America, Africa, Arabia, Madagascar, Sri Lanka, India, Antarctica, and Australia (Figure 1).
What animals lived on Gondwana?
Animal origins Groups that were probably part of the Gondwana fauna include tuatara, geckos, kākāpō, moa, wrens and some primitive groups of insects, spiders and earthworms.
What type of coal is present in Gondwana Supergroup?
80 out of 113 Indian coalfields are located in the rock systems of the Damuda series [lower Gondwana Age]. Coking as well as non-coking and bituminous as well as sub-bituminous coal are obtained from Gondwana coal fields. Anthracite is generally not found in the Gondwana coal fields.
What type of fossils are found in the Gondwanas?
The upper, Bhuj stage has yielded remains of conifer plants. Gondwanas have yielded a rich assemblage of animal and plant fossils that establish close relationship of Peninsular India with Australia, South America, South Africa and Madagascar etc. believed to have been a single continental unit during that span of time.
What are the characteristics of the Gondwana formation?
The Gondwana formations indicate varied depositional characteristics under varied palaeoclimatic conditions like glacial, fluvial, warm, and humid phase. The plant fossils are common in the Gondwana formations. Gondwana floral varieties were mostly climate-dependent.
Where are Gondwana rocks found in India?
The Gondwana rocks are traced along three large tracts in Peninsular and Central India: (i) In Bengal along the valley of Damodar. (ii) In Maharashtra along the Godavari River. (iii) In Madhya Pradesh, parallel to Mahanadi Valley.
Is there any flora in India like the Gondwana flora?
Indian plant fossils are known before (a few) and after (quite a large number) this period but no flora is as interesting as the Gondwana Flora. Towards the end of the Palaeozoic were the great Hercynian mountain building waves.
