Because, there are still so many amazing new dinosaur species discoveries. Here are 10 incredible dinosaur discoveries during 2021, summarized by LiveScience:
1. The First Dinosaur with a Perfect Cloacal Hole
Researchers have found all kinds of dinosaur remains, including bones, teeth, skin marks, and feathers. This is the first time paleobiologists from the University of Bristol in the UK have discovered the first dinosaur with a perfect cloacal opening.

According to a study published in the journal Current Biology in January 2021, this cloacal hole was used by dinosaurs to defecate, urinate, reproduce, and lay eggs. “This is the cloaca itself, formed in a perfect and unique way,” said Jakob Vinther, lead researcher in paleobiology at the University of Bristol, UK.
2. The Most T-rex Dinosaurs
–It is estimated that as many as 2.5 billion individual T-rexes lived during the last 2.5 million years of the Cretaceous period (145 million to 66 million years ago), before the killer asteroid collided with Earth. (Read also; Caterpillar with 1,300 Legs Found in Australia )
The researchers examined all the factors to determine this number, including the king dinosaur population density, habitat, generation time, and number of generations. According to a study in the journal Science published in April 2021, fewer than 100 individual T-rex fossils have been found.
3. Supersaurus, The Longest Dinosaur
–Supersaurus was recorded as the longest dinosaur, at about 39 meters (128 ft) and maybe even 42 meters (137 ft). According to unpublished research presented at the Society of Vertebrate Paleontology’s annual conference in 2021, Supersaurus was discovered in 1972.
Supersaurus has always been known for its length, even though this plant-eating dinosaur was about 34 meters (111 ft) tall. But now, freshly unearthed and analyzed bones reveal just how super-sized these dinosaurs were. (Read also; Train-sized Centipede Fossil Found in Newcastle )
4. Dinosaurs Young and Old in Groups on the Go
–A dinosaur grave found in Argentina reveals that long-necked dinosaurs from hatchlings the size of mice traveled together in groups 40 million years ago. Researchers found more than 100 fossilized eggs and bones from 80 individuals of Mussaurus patagonicus dating back 192 million years, during the Jurassic period (201.3 million to 145 million years ago).- .
