Taking stock of the eight best dinosaurs in the world

A type of reptiles that appeared in the Mesozoic era are called dinosaurs. Most of them had strong limbs, long tails and huge bodies. So what are the interesting record-breaking records in the huge and mysterious world of dinosaurs? If you want to know the best in the dinosaur world, you must read the following introduction!

1. Embryo

The world’s oldest dinosaur embryo

In 2003, a stone accidentally picked up at the Lufeng Dinosaur Camp in Lufeng, Yunnan Province caused such a stir. First, through micro-computed tomography, it was found to be a very early dinosaur embryo, and then it was subjected to two isotope dating , obtained a figure of 195 million years, confirmed to be the world's oldest dinosaur embryo.

2. Vertebrates

The world’s oldest terrestrial vertebrate embryo

Dinosaurs are the most representative terrestrial vertebrates (living on land) in the Mesozoic Era. In addition to being the oldest dinosaur embryos in the world, dinosaur embryos are also the oldest known terrestrial vertebrate embryos in the world.

3. Bone bed

The world’s oldest embryonic bone bed or hatchery

Dinosaurs are only one of the terrestrial vertebrates. Before there was any evidence of embryonic bone beds or hatcheries for other non-dinosaur terrestrial vertebrates, people deduced that dinosaurs were the oldest embryonic bone beds or hatcheries in the world.

4. Eggshell

The world’s oldest dinosaur eggshell

Dr. Koen from the University of Bonn in Germany accidentally discovered a hatching dinosaur eggshell while studying samples. It is the oldest dinosaur eggshell discovered so far.

5. Exercise

World’s oldest evidence of movement of hatching dinosaur embryos within eggs

From our study of Lufengosaurus embryos at different stages, we found evidence of movement within the eggs of the world's oldest hatching dinosaur embryos. It proves that the embryonic bone development of dinosaurs during the hatching stage was subject to the pulling movement of muscle growth, resulting in asymmetry in bone development (cross section of the thigh bone).

6. Residues

The world’s oldest organic residue

Early Jurassic dinosaur embryology in China carries evidence of preserved organic residues. We have discovered the oldest organic residues from these embryonic bones that are nearly 200 million years old.

7. Embryology

The world’s first dinosaur embryology

Academician Reitz studied the South African Massospondylus embryo published in 2005. He led the team to find many loose embryonic bones, cut and grind the bones, and pioneered dinosaur embryology in the world.
