family hadrosauridae การใช้

• "Altirhinus " is definitely an advanced iguanodontian, just basal to the family Hadrosauridae, but there is little agreement on the arrangement of genera and species in this area of the ornithopod family tree.
• Traditionally classified as an early member of the family Hadrosauridae, a 2008 analysis found " Claosaurus agilis " to be outside of the clade containing " Hadrosaurus " and other hadrosaurids, making it the closest not-hadrosaurid relative of true hadrosaurids within the clade Hadrosauria.
