shows that all three continents were once connected (joined) together. because the 'exact' same fossil types were found in all three different continents, which are now split from each other.
Glossopteris is a fossil plant:-The Glossopteridales arose around the beginning of the Permian on the great southern continent of Gondwana. These plants (which have distinctive spathulate fossil leaves with reticulate venation) went on to become the dominant elements of the southern flora through the rest of the Permian but disappeared in almost all places at the end of the Permian. The only convincing early Triassic records are leaves from Nidpur in India, but even these records are somewhat questionable owing to faulting and complex juxtapositioning of Permian and Triassic strata at Nidpur.
The first Smilodon fossils were discovered in the early 19th century, with documented findings as early as the late 1700s. These fossils were initially unearthed in North and South America.
Yes, fossils of early plants can provide valuable information about their adaptations, life cycle, and evolutionary history. By studying these fossils, scientists can better understand the diversity and ecology of early plant species and how they have influenced the development of ecosystems over time.
The remains of early life include fossils, traces of ancient organisms like footprints or burrows, and chemical signatures in rocks. These remains provide valuable insight into the evolution and diversity of life on Earth billions of years ago.
Early man scholars rejected fossils as a means to trace human evolution because they held religious or cultural beliefs that contradicted the idea of human evolution. Additionally, fossils were not well understood or widely accepted as evidence of human ancestry at the time.
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.

The early development of the theory of plate tectonics was supported by observations such as the fit of continents, similar rock formations across continents, and the distribution of earthquakes and volcanic activity along plate boundaries.
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in the early 20th century after observing cracks in the continents and similarities in rock formations and fossils across different continents.
The fit of the coastlines of different continents, the distribution of similar fossils across continents, and the presence of similar rock formations on different continents led early mapmakers to speculate that continents may have moved over time. This gave rise to the theory of continental drift, which was later developed into the theory of plate tectonics.

The plant genus that dominated glaciated regions during the late Paleozoic and early Mesozoic was Glossopteris. These plants were mainly gymnosperms that thrived in the ancient supercontinent of Gondwana. Their dominance in these regions is thought to be due to their adaptability to a range of environmental conditions.
