Fossil remains of Hyracotherium show it to have differed from the modern horse in three important respects: it was a small animal (the size of a fox), lightly built and adapted for running; the limbs were short and slender, and the feet elongated so that the digits were almost vertical, with four digits in the forelimbs and three digits in the ...
Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
Homo floresiensis (/ f l ɔːr ˈ ɛ z iː ˌ ɛ n. s ɪ s /), also known as "Flores Man" or "Hobbit" (after the fictional species), is an extinct species of small archaic humans that inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago.
Sicily and Malta were inhabited by two successive waves of dwarf elephants derived from P. antiquus, which first arrived on the islands at least 500,000 years ago. The first of these species is P. falconeri, which is one of the smallest dwarf elephant species at around 1 metre (3.3 ft) tall, and was strongly modified from its ancestor in numerous aspects, which lived in a depauperate fauna ...
Thus, island gigantism is usually an evolutionary trend resulting from the removal of constraints on the size of small animals related to predation and/or competition. [5] Such constraints can operate differently depending on the size of the animal, however; for example, while small herbivores may escape predation by hiding, large herbivores ...
A fossil preparator handles fossils found in Petrified Forest National Park at the museum's demonstration lab. Visitors are not allowed to take fossils from the park.
Classic paleoecology uses data from fossils and subfossils to reconstruct the ecosystems of the past. It involves the study of fossil organisms and their associated remains (such as shells, teeth, pollen, and seeds), which can help in the interpretation of their life cycle, living interactions, natural environment, communities, and manner of death and burial.
Garganornis ballmanni, a very large fossil goose from the Gargano and Scontrone islands of the Late Miocene. Foster's rule, also known as the island rule or the island effect, is an ecogeographical rule in evolutionary biology stating that members of a species get smaller or bigger depending on the resources available in the environment.
