In a matter so important as this, it has seemed thatpalaeontologists are entitled to the fullest possible knowledge of the specimens on which the conclusions are based.
All of these are, however, trilobites with small pygidia, and it has been a sort of axiom among palaeontologists that large pygidia were made up of a number of coalesced segments.
Most palaeontologists have not accepted this explanation, and since the so-called eyes cover only a part of the surface of the maculae, it is still possible to consider the latter as chiefly muscle-scars.
From the fact that the breccia yielded a number of supposed extinct species of plants, palaeontologists were inclined to assign it to the Pliocene.
This is now admitted by Continental palaeontologists who find in the character of Pleistocene organic remains abundant proof that the old river-alluvia and cave-accumulations were laid down under changing climatic conditions.
These details sound like the descriptions given by palaeontologists of the first appearance, the increasing rarity, and final extinction or modification of fossil species, embedded in the successive stages of a geological formation.
If the several vertebrae of the wild and lop-eared rabbits, of which figures have been given, had been found fossil, palaeontologists would have declared without hesitation that they had belonged to distinct species.
A large majority of palaeontologists would answer in the affirmative; and it seems that this answer must be admitted as true, though difficult of proof.
But Sir Charles Lyell now gives the support of his high authority to the opposite side, and most geologists and palaeontologistsare much shaken in their former belief.
It is notorious on what excessively slight differences many palaeontologists have founded their species; and they do this the more readily if the specimens come from different sub-stages of the same formation.
The case most frequently insisted on by palaeontologists of the apparently sudden appearance of a whole group of species, is that of the teleostean fishes, low down, according to Agassiz, in the Chalk period.
By many able palaeontologists the species of fossils, more than fifty in number, were declared to be more Eocene in their appearance than Cretaceous.
The tooth-marks of these last had been detected by palaeontologists long before on the bones and skulls of Paleotheres entombed in the gypsum.
Even in our own day, most palaeontologists examine and describe fossils without knowing the most important facts of embryology.
A large number of palaeontologists would answer in the affirmative; and it seems that this answer must be admitted as true, though difficult of proof.
Belgian palaeontologists have also been active in their study of fishes.
The case most frequently insisted on by palaeontologists of the apparently sudden appearance of a whole group of species, is that of the teleostean fishes, low down in the Chalk period.
Lately, Professor Pictet has carried their existence one sub-stage further back; and some palaeontologists believe that certain much older fishes, of which the affinities are as yet imperfectly known, are really teleostean.
If the doctrine of evolution had not existed,' says Huxley, 'palaeontologists must have invented it.
It was first carried out in detail by various palaeontologists in reference to the Jurassic formations, notably by F.
Marcel de Serres as new; but the majority of palaeontologists do not agree with this opinion.
As some of our zoologists and palaeontologists may have somewhat to say upon this matter, we leave it for their consideration.
With respect to the first proposition, I may remark that whatever may be the case among the physical geologists, catastrophic palaeontologists are practically extinct.
Palaeontologists favour the idea that the Plesiosaurus and its allies were air-breathing creatures with long necks, adapted to habitual projection above the surface.
Great differences of opinion have existed among palaeontologists as to whether they are more reptilian than bird-like, or even mammalian.
Mr. Dollo, of Brussels, is preparing a final monograph on the Bernissart Iguanodons, a work to which palaeontologists eagerly look forward.
Notwithstanding a vast amount of observation on the subject, considerable differences of opinion have prevailed among palaeontologists with regard to the proper relation of the Mastodon to the Mammoth and living elephants.
Palaeontologists have good reason to believe that they were descended from some early form of land reptile.
Mantell, the enthusiastic geologist to whose labours palaeontologists are greatly indebted, had previously discovered similar teeth and bones in the Wealden strata of Tilgate Forest.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "palaeontologists" in a variety of sentences. We hope that you will now be able to make sentences using this word.
