Ichthyosaurs

Ichthyosaurs, often referred to as "fish-lizards," were a group of marine reptiles that thrived during the Mesozoic Era. These fascinating creatures evolved into highly specialized marine predators, with streamlined bodies, powerful tails, and large eyes. Their appearance and lifestyle were remarkably similar to modern dolphins and whales, despite being unrelated.

Ichthyosaurs first appeared in the Triassic Period and diversified into a variety of forms, ranging from small, eel-like species to large, dolphin-like predators. Their remarkable adaptations to marine life included giving birth to live young, a trait shared with modern whales and dolphins. This adaptation allowed ichthyosaurs to avoid the dangers of laying eggs on land.
