Based on Guericke’s writings, Leibniz drew a fictional reconstruction of the unicorn's skeleton using the bones that had been found in the cave and published the drawing in his book Protogaea. In 1872, Rudolf Virchow carried out an excavation there and determined that the unknown bones actually stem from extinct animals like mammoths and cave ...
[27] [28] For example, most extinct animals' coloration and patterning are unknown from fossil evidence, but these can be plausibly restored in illustration based on known aspects of the animal's environment and behavior, as well as inference based on function such as thermoregulation, species recognition, and camouflage.
The best known Elasmotherium species, E. sibiricum, sometimes called the Siberian unicorn, [4] was among the largest known rhinoceroses, with an estimated body mass of around 4.5 tonnes (9,900 lb), comparable to an elephant, and is often conjectured to have borne a single very large horn. However, no horn has ever been found, and other authors ...
In 1903, Hungarian palaeontologist Franz Nopcsa von Felső-Szilvás suggested that the fragmentary domes of Stegoceras were in fact frontal and nasal bones, and that the animal would therefore have had a single, unpaired horn. Lambe was sympathetic to this idea of a new type of "unicorn dinosaur" in a 1903 review of Nopscsa's paper.
Euteleostomes originally all had an endochondral bone, fins with lepidotrichs (fin rays), jaws lined by maxillary, premaxillary, and dentary bones composed of dermal bone, and lungs. Many of these characters have since been lost by descendant groups, however, such as lepidotrichs lost in tetrapods , and bone lost among the chondrostean fishes.

Soon after this, two more, nearly complete specimens were discovered in the Dapingfang area, about 40 kilometres (25 mi) from the original fossil site. None of these first three specimens preserved traces of feathers, but based on the size of their skeletons alone, they were recognized as the largest early Cretaceous avialans known at the time. [9]
