Macrocollum suture. "Macrocollum", alongside "Jaklapallisaurus" and "Unaysaurus", was found to belong to the clade Unaysauridae. "Macrocollum" lived between about 225.42 to 225 million years ago, in the Norian age of the late Triassic period. It was found in the south of Brazil, which at the time was connected to northwest Africa. At the time, most of the Earth's landmass was united into the supercontinent Pangaea, which was just starting to divide into Laurasia in the north, and Gondwana in the south. U-Pb (Uranium decay) dating found that the Caturrita Formation dates to around 225.42 million years ago, making it fewer than
Mandla Plant Fossils National Park some work on the plant fossils of Mandla, though the study is yet in a preliminary stage. In Ghuguwa and Umaria the standing, petrified trunks of trees have been identified as Gymnosperms and Angiosperms- Monocotyledons and palms. There are certain Bryophytes also. There is some question about whether the fossils are from the late Jurassic or the early and mid Cretaceous age. This is because when the breakup of the single land mass, Pangaea occurred, it was split by the continental drift into Laurasia and Gondwana somewhere between the Jurassic and Cretaceous ages. India formed a part of Gondwana. Depending
