Description

Description: Phylum: Chordata Class: Aves Order: Unknown Genus: Unknown Common Name: Bird Egg Age: Unknown Location: Gold Hill, OR Description: Oval shape with peeling layers and a hole (.500") on one side. Dull yellow to tan. Physical Characteristics: Birds (class Aves) are feathered, winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. Around 10,000 living species makes them the most speciose class of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic. Extant birds range in size from the 5 cm (2 in) Bee Hummingbird to the 2.75 m (9 ft) Ostrich. The fossil record indicates birds evolved from theropod dinosaurs during the Jurassic period, around 150–200 million years (Ma) ago, and the earliest known bird is the Late Jurassic Archaeopteryx, around 150–145 Mya (million years ago). Most paleontologists regard birds as the only clade of dinosaurs to have survived the Cretaceous–Tertiary extinction event approximately 65.5 Mya.
