This ankylosis usually involves two to six elements and in many cases, also includes the last cervical vertebra. Fusion can occur in different degrees, uniting the vertebral centra, the neural spines, the transverse ...

Реконструкция шеи Azhdarcho lancicollis и образ жизни аждархид (Pterosauria, Azhdarchidae)

Палеонтологический журнал, 2013
Компьютерная реконструкция изолированных шейных позвонков Azhdarcho lancicollis из турона Узбекистана позволила создать трехмерную модель шейного отдела позвоночника этого животного. Относительная длина шейных позвонков (I + II VI > VII > VIII > IX) такая же, как у птеродактилоидов с неудлиненными шейными позвонками.
