How did the iguanodon become extinct?

Iguanodon, a herbivorous dinosaur from the Late Jurassic to Early Cretaceous periods, likely faced extinction due to a combination of factors. These included significant environmental changes, such as climate shifts and habitat loss, as well as competition with other species and predation pressures. Additionally, the mass extinction event at the end of the Cretaceous period, which wiped out around 75% of Earth's species, including many dinosaurs, played a crucial role in their demise.
