Answer:
The thylacine, also known as the Tasmanian tiger, was a carnivorous marsupial native Tasmania, Australia, and New Guinea. had a dog-like appearance with yellowish-brown fur, dark stripes across its back, and a stiff tail. The thylacine became extinct primarily due to habitat loss, hunting, and disease introduced by European settlers. The last known thylacine died in captivity in 1936.
Golden toads were brightly colored amphibians found only in the Monteverde Cloud Forest of Costa Rica. They had bright orange skin with black spots and were relatively small in size. The golden toad became extinct in the late 1980s, and the exact reason for its extinction remains uncertain. However, it is believed that a combination of climate change, habitat loss, and a fungal disease called chytridiomycosis contributed to its decline.
Trilobites were a diverse group of marine arthropods that lived from the Cambrian period to the Permian period, approximately 520 to 250 million years ago. They had a hard exoskeleton and multiple segments, resembling modern-day horseshoe crabs. Trilobites became extinct due to major environmental changes, including glaciation, sea-level fluctuations, and oceanic changes. Additionally, competition with other marine organisms and predation may have also played a role in their extinction. The exact cause and timing of trilobite extinction are still debated among scientists.
An asteroid impact is believed to have played a significant role in causing mass extinctions on Earth, including the extinction of dinosaurs. The most famous example is the Chicxulub impact event, which occurred approximately 66 million years ago. The impact of a massive asteroid in what is now the Yucatan Peninsula in Mexico released an enormous amount of energy, leading to global fires, an impact winter, and drastic climate changes. These environmental changes caused the extinction of various species, including the non-avian dinosaurs.
