“Mini” Dino Found in Germany - Europasaurus holgeri
A dwarf sauropod has recently been described by paleontologists. Holger Luedtke, a paleontology hobbyist first came across teeth and other remains of a herbivorous dinosaur in a quarry near in North Germany in 1998.
At the time, scientists thought they may be juveniles. However, Dr. Martin Sander, who is an expert on the micro-structure of dinosaur skeletons, studied the bones and concluded that they were adults. In short, he was able to measure rings of growth in the bones. Rings are spaced further apart when the dinosaurs are young and growing rapidly. As they age the space between the rings becomes smaller.
When first found the dino was nicknamed ‘Hanna’, but has now been given the new and official scientific name Europasaurus holgeri, in honor of its discoverer. It essentially means Holger’s reptile of Europe.
So how mini was it? Well, the diagram below shows it was still pretty big compared to a human. But it was quite tiny when compared to one of its closest cousins the Apatosaurus (aka Brontosaurus) who was among the largest land animals that ever existed.
The paper describing the new species was published in Nature.
