The fossils will be carbon-dated and analyzed to figure out the mastodon’s age, diet and habitat, officials said. Staff at SUNY Orange pulled the mastodon jaw from the ground. Akkharat J ...
A 1.4-million-year-old fossil jaw discovered in a South African cave in 1949 has now been identified as that of a previously unknown human relative species dubbed the “nutcracker man”.
A complete mastodon jaw was discovered in the backyard of a home in New York's Hudson Valley, marking the state's first such find in more than a decade, officials announced this week.
A scolecodont is the jaw of a polychaete annelid, a common type of fossil-producing segmented worm useful in invertebrate paleontology. Scolecodonts are common and diverse microfossils, which range from the Cambrian period (around half a billion years ago at the start of the Paleozoic era) to the present.
The sides of upper jaw are lined with a double row of small conical teeth, while the lower jaw has a single row of similar small teeth. The upper and lower arrangement of small, narrow teeth could function like a trap for small prey when Mastodonsaurus closed its mouth. The tip of the upper jaw has a set of larger teeth.
Dimetrodon (/ d aɪ ˈ m iː t r ə ˌ d ɒ n / ⓘ [1] or / d aɪ ˈ m ɛ t r ə ˌ d ɒ n /; [2] lit. ' two measures of teeth ') is an extinct genus of sphenacodontid synapsid tetrapods that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago.
Entelognathus primordialis (“primordial complete jaw”) is an early placoderm from the late Silurian (Ludlow epoch) of Qujing, Yunnan, 419 million years ago. [2] [1]A team led by Min Zhu of the Academy of Sciences' Institute of Vertebrate Paleontology and Paleoanthropology in Beijing discovered the intact, articulated fossil in rock formations at Xiaoxiang reservoir.
Scientists said this ichthyosaur lived 205 million years ago and dominated the oceans just as dinosaurs were becoming masters on land.
