What's the difference between carboniferous and graptolite?
Carboniferous
Definition:
(a.) Producing or containing carbon or coal.
Example Sentences:
(1) As the time of divergence of at least some of these gymnosperm taxa is traceable back to the early Carboniferous, it may be concluded that the genealogical splitting of gymnosperm and angiosperm lineages occurred before this event, at least 360 million years ago, i.e., much earlier than the first angiosperm fossils were dated.
(2) This period marks the end of the Devonian, often referred to as the “age of fish”, and the beginning of the Carboniferous.
(3) – Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous … 'What will survive of us is love', wrote Philip Larkin.
(4) Although it is the earliest and most primitive reptile yet known, it is probably already too late and too specialized to be ancestral to the more advanced Carboniferous and Permian captorhinomorphs and pelycosaurs.
(5) Recent work on Silurian, Devonian and Carboniferous terrestrial assemblages has provided plausible evidence for all major groups of extant fungi in the Paleozoic.
(6) Eighty million years later, at the start of the Carboniferous, the first land plants bloomed.
(7) 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.
(8) Previous accounts of the dentition of the Carboniferous dipnoan Uronemus have stressed the significance of the scattered small denticles.
(9) Because the Carboniferous deposits at Joggins, Nova Scotia, contain the earliest fauna of terrestrial vertebrates, the extremely well-preserved teeth of these ancient animals are of special interest.
(10) Kühne first worked on fissures in the Carboniferous limestone quarries at Frome, Somerset, in southwest England where he collected a series of teeth of the problematical form Haramiya and two triconodont teeth which were placed in the genus Eozostrodon (Parrington 1941, 1946).
(11) Perhaps it was marvelling at Zallinger's famous Yale University mural of a Carboniferous landscape as a child that makes me associate tree ferns with an earlier geologic time.
(12) This paper presents the results of the comparative evaluation of the structure and sorption properties of fibrous (AYBM- -MH) and granulated (CKH-IK) carboniferous sorbents.
Graptolite
Definition:
(n.) One of numerous species of slender and delicate fossils, of the genus Graptolites and allied genera, found in the Silurian rocks. They belong to an extinct group (Graptolithina) supposed to be hydroids.
Example Sentences:
(1) Wow!” (Graptolites and trilobites are long-extinct marine animals).
(2) And if it is, the exciting thing is: what about all those graptolites – what if they were luminous?
(3) These long and short fibres have features in common with those found in the graptolites.
