Add a definition The detailed descriptions and illustrations provide an anatomical atlas that will be of great help to those working ontetrapodevolution and interrelationships. From theCambridge English Corpus Stratigraphic ranges of the principaltetrapodtaxa are indicated. From theCambridge English Corpus Firstly, the high density of the lepidosaur populations results from a low species diversity and the island tetrapods therefore expand their niche space. From theCambridge English Corpus In short this is an excellent and comprehensive account of the state of our knowledge of this important, and often neglected, group of tetrapods. From theCambridge English Corpus What can explain the death of great numbers of lepidosaurs and other small tetrapods that are transported as articulated skeletons and/or numerous individual bones? From theCambridge English Corpus In fact, the scope of the volume reaches even wider, as it closes with a section on stem tetrapods and fossil amphibians. From theCambridge English Corpus Most of the individual chapters fall into the second category: all of the majortetrapodgroups are considered, ranging from temnospondyls to marsupials. From theCambridge English Corpus Perhaps there were a number of factors both biotic and abiotic involved in the death of the tetrapods. From theCambridge English Corpus However, even nearby islands are unlikely to have the sametetrapodcomponents living contemporaneously, and some species may never reach some localities. From theCambridge English Corpus There are previous reports where site-specificity has been correlated with monogenean development, but these relate mostly to polystomatids fromtetrapodhosts. From theCambridge English Corpus Nonetheless, all reptiles and birds are classified as diapsids just as, for example, legless lizards and snakes are classified as tetrapods. From theCambridge English Corpus The two cetacean suborders have evolved for 50 million years from a commontetrapodancestor. From theCambridge English Corpus More recent work on amphibians presents something of a puzzle and a surprise, however, concerning thalamic evolution within this clade and within tetrapods. From theCambridge English Corpus Therefore, there is clear evidence for forest fires in both sauropsid and mammal-bearing fissures that provides a plausible explanation for the death of the tetrapods. From theCambridge English Corpus Twenty-three chapters are presented sequentially from basal chordates and vertebrate origins through to tetrapods. From theCambridge English Corpus The chapters dealing with the evolution of thetetrapodlimb were particularly well written, expressing the complexities of limb-bud formation and differentiation with clear, jargon-free prose. From theCambridge English Corpus He interprets the hindlimb as pentadactyl with extra 'interdigital' structures and does not accept the suggestion that polydactyly, and not pentadactyly, is primitive for tetrapods. From theCambridge English Corpus Zimmer chooses to concentrate on two macroevolutionary events that have long puzzled zoologists and palaeontologists: the origin of tetrapods and the origin of whales. From theCambridge English Corpus The absence of abundant insect remains does not seem to us a significant impediment to the forest fire theory which otherwise explains the origination of thetetrapodfossils so well.
