What was an elasmosaurus life span?

Elasmosaurus, a long-necked marine reptile from the Late Cretaceous period, likely had a life span of around 20 to 30 years, similar to many modern reptiles. Its size and ecological niche suggest it had a relatively stable life, thriving in marine environments. However, specific data on its age and longevity remain sparse due to the limitations of the fossil record.
