dinornis उदाहरण वाक्य
उदाहरण वाक्य
- Located above Kiwi Pass and at the southern end of Kent Plateau, it was named after an extinct and flightless bird species in New Zealand, the moa ( " Dinornis gigantea " ).
- The large " Dinornis " species took the same length of time to reach adult size as small moa species, and as a result had an accelerated rate of skeletal growth during their juvenile years.
- Moreover, sex-specific DNA recovered from the outer surfaces of eggshells belonging to species of " Dinornis " and " Euryapteryx " suggest that these very thin eggs were likely to have been incubated by the lighter males.
- At least three other genera ( " Dinornis ", a mastodon, and " Glyptodon " ) were planned, and Hawkins began to build at least the mastodon before the Crystal Palace Company cut his funding in 1855.
- Models of the " fearfully great bird " " Dinornis " of New Zealand ( extinct by 1500 AD ), and of the extinct elephant-like " Mastodon " ( Deinotherium ) of the Miocene and Pliocene of America, were planned for the'Tertiary Islands'but not completed.
- Therefore, the three species of " Dinornis " were reclassified as two species, one each formerly occurring on New Zealand's North Island ( " D . novaezealandiae " ) and South Island ( " D . robustus " ); " D . robustus " however, comprises three distinct genetic lineages and may eventually be classified as many species, as discussed above.
- A 2010 study by Huynen et al . has found that the eggs of certain species were fragile, only around a millimeter in thickness : " Unexpectedly, several thin-shelled eggs were also shown to belong to the heaviest moa of the genera " Dinornis ", " Euryapteryx ", and " Emeus ", making these, to our knowledge, the most fragile of all avian eggs measured to date.
- One factor that has caused much confusion in moa taxonomy is the intraspecific variation of bone sizes, between glacial and inter-glacial periods ( see Bergmann s rule and Allen s rule ) as well as sexual dimorphism being evident in several species . " Dinornis " seems to have had the most pronounced sexual dimorphism, with females being up to 150 % as tall and 280 % as heavy as males & mdash; so much bigger that they were formerly classified as separate species until 2003.
- When the first specimens were originally described by Richard Owen, they were placed within the genus " Dinornis " as three different species, but, was later split off into their own genus, " Emeus " . " E . crassus " is currently the only species of " Emeus ", as the other two species, " E . casuarinus " and " E . huttonii " are now regarded as synonyms of " E . crassus ".
- The documentary was filmed at the Natural History Museum, London, and uses CGI imagery to bring to life several of the extinct animal skeletons in the museum, including " Archaeopteryx ", the Moa Ratite bird ( " Dinornis " ) and Haast's eagle ( " Harpagornis moorei "; lit . " grappling hook bird " ), " Gigantopithecus " ( presented as more human than ponginae ), " Glossotherium ", " Ichthyosaurus " and Dippy, a replica of a famous " Diplodocus " skeleton.
