Fossils explained 54
Plesiosaurs may be divided into two general morphotypes, based on body shape. ‘Pliosauromorphs’ have a large head and a short neck—traditionally thought to be pliosaurs, while ‘plesiosauromorphs’ have a small head and long neck, and have been seen as plesiosauroids. This is in fact an oversimplification, and today, detailed analysis and investigations of plesiosaur anatomy suggest that these mo...
متن کاملStratigraphy, correlation, and age estimates for fossils from Area 123, Koobi Fora.
Geological data from the Bura Hasuma region at Koobi Fora provide important constraints for estimating the ages of hominin fossils recovered there, including the cranium KNM-ER 1813. Strata of the upper Burgi, KBS, and Okote members in this part of Koobi Fora reflect three depositional regimes driven by changing paleogeography through time. The upper Burgi and lowermost KBS sequence in the sout...
متن کاملDrawings of Fossils by Robert Hooke and Richard Waller
The drawings of fossils by Robert Hooke and Richard Waller that were the basis of the engravings in Hooke’s Posthumous works (1705) are published here for the first time. The drawings show that both Hooke and Waller were proficient draftsmen with a keen eye for the details of petrified objects. These drawings provided Hooke with a polemic edge in making the case for the organic origins of ‘figu...
متن کاملSurvival of fossils under extreme shocks induced by hypervelocity impacts
Experimental data are shown for survival of fossilized diatoms undergoing shocks in the GPa range. The results were obtained from hypervelocity impact experiments which fired fossilized diatoms frozen in ice into water targets. After the shots, the material recovered from the target water was inspected for diatom fossils. Nine shots were carried out, at speeds from 0.388 to 5.34 km s(-1), corre...
متن کاملFossils and plant phylogeny.
Developing a detailed estimate of plant phylogeny is the key first step toward a more sophisticated and particularized understanding of plant evolution. At many levels in the hierarchy of plant life, it will be impossible to develop an adequate understanding of plant phylogeny without taking into account the additional diversity provided by fossil plants. This is especially the case for relativ...
