Pentacrinites are commonly found in the Pentacrinites Bed of the Early Jurassic (Lower Lias) of Lyme Regis, Dorset, England. [2] Pentacrinites can be recognized by the extensions (or cirri) all around the stem, which are long, unbranching, and of increasing length further down, the very small cup and 5 long freely branching arms.
It is known that the arms could shut tightly in life (most Encrinus fossils are found in this position), but it is difficult to estimate the greatest angle at which they could open. It is possible that specimens recorded as being widest open demonstrate the normal angle of opening in life. [ 3 ]
[66] [67] Burned wood has been found in layers that carried the Java Man fossils in Trinil, dating to around from 500,000 to 830,000 BP. However, because Central Java is a volcanic region, the charring may have resulted from natural fires, and there is no conclusive proof that Homo erectus in Java controlled fire. [ 65 ]
“The last 50 years of fossil discoveries have made it clear that there wasn’t a single hominin lineage around at any point in the past (making humans today quite unique),” said Carrie Mongle ...
The log structure was made at least 476,000 years ago, while the wood tools are slightly younger, under 400,000 years old. That places the materials in a time before our species, Homo sapiens ...
Fossil crinoid. This list of crinoid genera is an attempt to create a comprehensive listing of all genera that have ever been considered to be crinoids, excluding purely vernacular terms.
By 1990, about 600 human remains were reported, and by 2004 the number had increased to roughly 4,000. These represent at least 28 individuals, of which possibly only one is a child, and the rest teenagers and young adults. The fossil assemblage is exceptionally complete, with whole corpses buried rapidly, and all bodily elements represented. [10]
A recent analysis of fossils belonging to Homo floresiensis found at the Mata Menge site on Flores supports the idea that the hobbits were a dwarfed version of the extinct species Homo erectus.
