rachitrema造句

• The ichthyosaur nature of " Rachitrema " was recognized by Friedrich von Huene, who synonymized it with " Shastasaurus ".
• Sauvage conceded that " Rachitrema " was non-dinosaurian, and the ichthyosaur classification of the genus became universally accepted by several authors.
• However, recent re-examination of the type material of " Rachitrema " reaffirms the ichthyosaurian classification of the genus, with most of the original remains referable to Ichthyosauria, and the rest being indeterminate beyond Reptilia.
