In Depth It could be said that Jobaria is a sauropod that doesn’t know what it is due to a mix of different traits. The vertebrae of Jobaria are very simple in form which has led to some suggestion that Jobaria is a primitive sauropod. Study of other areas however has led to speculation that … Read more

The two main options at the moment are that either Lamplughsaura represents a very advanced sauropodomorph, or a primitive sauropod dinosaur. What can be established however is that Lamplughsaura does represent a transitional … Read more
