| The aetosaurs, or Stagonolepididae, were large herbivorous armoured archosaurs, and an important characteristic part of Late Triassic faunas. |
|
| The study of zoogeography attempts to answer questions about how and why fish faunas differ across geographic regions. |
|
| Relatively little work has been done recently on decapod faunas from the Middle East. |
|
| The sediments are noted for their rich ammonoid faunas, which allow detailed biostratigraphic subdivision and correlation. |
|
| The overall fauna is not very diverse compared with coeval faunas from central Asia documented by Holmer et al. |
|
| With the specific exception of river margin faunas, the more fussy hygrophilous species are well represented in Ireland. |
|
| Others have suggested that there is nothing unusual about Cambrian faunas in terms of their flexibility or disparity. |
|
| Floras and faunas from these beds have been discussed, but the remains of small vertebrates have received little attention. |
|
| In the northern hemisphere, marine floras and faunas show a clear differentiation into two realms, Tethyan and Boreal. |
|
| Furthermore, trilobite faunas in the Early Cambrian were already differentiated biogeographically. |
|
| It is biogeochemistry that lends substance to the hypothesis that Ediacaran and Cambrian faunas are separated by mass extinction. |
|
| Perhaps the reason is that social bees, which are largely opportunistic, dominate pollinator faunas in northern regions. |
|
| When dwarf faunas are found in the fossil record, they are invariably associated with times of environmental stress. |
|
| This book held all of his doodles, sketches, and documentations on the many floras and faunas of the worlds he trekked. |
|
| The Ordovician faunas described herein represent both the Midcontinent and Atlantic faunal realms. |
|
| This section is highlighted by excellent summaries of the major biogeographic realms and their endemic faunas. |
|
| These divisions reflect major changes in the composition of ancient faunas, each era being recognized by its domination by a particular group of animals. |
|
| Early Carboniferous coral faunas of the block have a strong Eurasian affinity, with two recognized coral faunas from two ecological facies having been recognized. |
|
| Postulated as basal lunulate taxa, the monophorasterids are very important to our understanding of major events in the origins of the New World sand dollar faunas. |
|
| The late Ordovician brachiopods have been monographed by Villas, who detected a genetic, but not very close, similarity with Armorican and Perunican faunas. |
|
|
|
| It is apparently absent from Triassic faunas of northeastern Asia and the Boreal region, and until now has not been reported from the Triassic of the Americas. |
|
| Eurypterid associations can often be distinguished and related to environmental conditions, such as marine, lagoonal or estuarine, or brackish to freshwater faunas. |
|
| Despite its relatively small size, Massachusetts hosts one of the most diverse odonate faunas known from any state, with at least 164 species recorded to date. |
|
| The projects to create electronic floras and faunas complement other major international initiatives designed to better understand and manage the world's natural heritage. |
|
| The tiny conical shells known as dacryoconarids were also abundant and evolving rapidly at this time, but only a few dendroid graptoloids remained from the Silurian faunas. |
|
| Also as seen in graptolites, many of the taxa that were common during the Hirnantian were eurytopic species, high-latitude immigrants, or endemic, relict faunas. |
|
| Both marine and continental faunas were essentially modern, although continental faunas were a bit more primitive than today. |
|
| Ostracoderm faunas of the Delorme and associated Siluro-Devonian formations, North West Territories, Canada. |
|
| The diversity of this assemblage is similar to that of modern crustacean faunas. |
|
| Neotropical tree species and their faunas of Xylophagous longicorns in French Guiana. |
|
| Stratigraphy and faunas of the Parautochthon and Lower Allochthon of southern Norway. |
|
| Marine faunas became fairly modern, as did terrestrial vertebrate fauna on the northern continents. |
|
| For the first time foraminifera take a prominent part in the marine faunas. |
|
| Over 400 species of birds have been reported from the region, and the reptile and amphibian faunas are similarly rich. |
|
| Upper Ordovician hardground faunas were dominated by bryozoans and echinoderms, but cornulitid tubeworms and sphenothallids were also common. |
|
| The Grande Coupure marks a break between endemic European faunas before the break and mixed faunas with a strong Asian component afterwards. |
|
| Most of the continental fragments, volcanic arcs, and ocean basins added to Laurentia this way contained faunas of Tethyan or Asian affinity. |
|
| There appears to have been a land bridge in the early Oligocene between North America and Europe, since the faunas of the two regions are very similar. |
|
| Late Ordovician to Early Silurian conodont faunas from the Kolyma terrane, Omulev Mountains, Northeast Russia, and their paleobiogeographic affinity. |
|
| Carbonate hardgrounds were thus very common, along with calcitic ooids, calcitic cements, and invertebrate faunas with dominantly calcitic skeletons. |
|
|
|
| The lingulate brachiopod faunas documented from the Paltodus deltifer Biozone of the Eastern Alborz Mountains and Poland show clear signs of the beginning of recovery. |
|
| But arguing against this is a recent study of North American faunas. |
|
| During the Cenozoic, North America was periodically connected to Eurasia via Beringia, allowing multiple migrations back and forth to unite the faunas of the two continents. |
|
| There were three general dinosaur faunas in the late Cretaceous. |
