The holotype specimen (TMP 2007.0110001) consists of an almost complete skeleton lacking a skull. The neck contains 76 cervical vertebrae. This is a unique character of Albertonectes vanderveldei and the highest number of neck vertebrae known for any plesiosaur, surpassing the previous record-holder (Elasmosaurus) by four vertebrae.

The distal-most caudal vertebrae (27th to 33rd) ofAlbertonectes are fused into a pygostyle-like structure.
