What's the difference between devonian and paleozoic?
Devonian
Definition:
(a.) Of or pertaining to Devon or Devonshire in England; as, the Devonian rocks, period, or system.
(n.) The Devonian age or formation.
Example Sentences:
(1) Modern lungfish are air-breathing nonmarine forms, yet their Devonian forebears were marine fish that did not breathe air.
(2) The Siluro-Devonian "explosive" colonization of land, and indeed the very evolution of plants, was possible only through such mutualistic partnerships-partnerships that were equipped to cope with the problems of desiccation and starvation associated with terrestrial existence.

(8) The dental plates of the Devonian lungfish Chirodipterus australis Miles (Osteichthyes; Dipnoi) are shown to have achieved their characteristic morphology by a growth process different from that assumed for the plates of genera such as Dipterus.
(9) Recent work on Silurian, Devonian and Carboniferous terrestrial assemblages has provided plausible evidence for all major groups of extant fungi in the Paleozoic.
(10) Fossils dating from the time of origin of tetrapods in the Devonian offer the only hope of understanding the morphological innovations that led to tetrapods; morphological analysis of the "living fossils," the coelacanth and lungfish, only lends confusion.
(11) Here I report the discovery of the stapes of Acanthostega gunnari, from the Upper Devonian of east Greenland.

(13) Evolution of life coincides with the most rapid rate of rise in atmospheric oxygen concentration during Devonian time.
(14) Morphologically, sharks are living fossils that are remarkably similar to their Devonian ancestors of ca.
(15) These, together with the marginal teeth and ridges, have been interpreted as primitive characters of the dipnoan dentition shared with three other genera: the Devonian Uranlophus and Griphognathus and the Carboniferous to Permian Conchopoma.
(16) Devonian vertebrates include a wide range of endemic forms, which provide evidence of more than six distinct biostratigraphic assemblages in South China and five biogeographical realms.
(17) The 51-year-old Devonian mother of two was being wooed by Harold Tillman, the retail magnate who had recently bought the historic British Jaeger clothing brand, over a series of high teas at Claridge's.
(18) Further comparison of the results with similar experimental findings in members of other vertebrate classes supports the notion that several of these same pathways can be traced to even more remote ancestry, with some possibly as old as the entire vertebrate subphylum--dating from the early Devonian or before, perhaps 430 million years ago.
(19) The spatial arrangement of the vertical canals is already present in fossil ostracoderms, and is also exemplified in lampreys, the modern forms of once abundant agnathan species that populated the Silurian and Devonian oceans.
(20) A review of the vertebrates within the Silurian and Devonian of China suggests a more detailed picture of palaeobiogeographical distribution than previously possible.
Paleozoic
Definition:
(a.) Of or pertaining to, or designating, the older division of geological time during which life is known to have existed, including the Silurian, Devonian, and Carboniferous ages, and also to the life or rocks of those ages. See Chart of Geology.
Example Sentences:
(1) The geographic location of leptospirosis presents a pattern which closely parallels the distribution of Paleozoic bedrock.
(2) In general, the small subunit nuclear sequences appear to be best for elucidating Precambrian divergences, the large subunit nuclear sequences for Paleozoic and Mesozoic divergences, and the organellar sequences of both subunits for Cenozoic divergences.
(3) Recent work on Silurian, Devonian and Carboniferous terrestrial assemblages has provided plausible evidence for all major groups of extant fungi in the Paleozoic.
(4) Of the suborders present in the Paleozoic, seven are morphologically relatively simple, slowly evolving, and continued into Mesozoic and Cenozoic times to become the ancestoral lineages from which evolved several additional post-Paleozoic suborders.
(5) Key events in fungal macroevolution thus probably took place in the early Paleozoic or the late Precambrian, and the likelihood of finding definitive fossil evidence for them is small.
(6) The approximately 300 million years that make up Paleozoic time saw the evolution of eight of the fifteen recognized suborders of Foraminifera.
(7) The preliminary implication of these observations is that the mechanism of physiological color change involving MCH and its melanophore receptors evolved near the end of the Paleozoic or during the early Mesozoic, just before or early in the evolution of neopterygian (holostean and teleostean) fishes.
(8) Their early representatives may have given rise to three and eventually four post-Paleozoic suborders.
(9) The widespread late Paleozoic condition of seasonal drought favored progressive developments which, with the attainment of a reptilian stage, had the happy accidental result of the vertebrate conquest of the land, a conquest aided by the emergence of the insects as a basic food supply.
(10) A number of suborders in the Paleozoic have similar, supposedly independent, early evolutionary patterns with the following series of morphological steps: (1) single chambers with or without apertures depending on the amount of wall cement; (2) groups of chambers that appear to be buds or aggregations of individuals rather than true chambers; (3) a proloculus followed by a tubular second chamber that is first erect and gradually evolves into enrolled free-living individuals; (4) development of constrictions in the tubular chamber; and finally (5) evolution of true chambers.
(11) Fusulinines became extinct at the end of the Paleozoic.
(12) In Ontario, bedrock composed of limestone and dolomite formed in the Paleozoic era appears to be a reliable ecological marker for Leptospira pomona infection.
(13) In contrast, an eighth Paleozoic suborder, the Fusulinina, was an abundant, ecologically dominant group that evolved from simple to highly specialized forms and had a history of rapid evolution with diverse lineages.
(14) Antibodies to L. hardjo and L. sejroe occur in many bovine sera from a predominantly Precambrian area where Paleozoic outliers are numerous.
(15) A marked increase in atmospheric oxygen level near the beginning of the Paleozoic would eliminate oxygen-collagen priorities simultaneously and on a world-wide basis in all metazoan stocks providing evolutionary pressure for enlarged musculatures and associated "hard parts."
