👉 Bathynellacea is a genus of extinct aquatic animals from the Mesozoic era, characterized by their large, elongated bodies and adaptations for swimming in water. Some species were herbivorous, while others had teeth adapted for cutting through plant material or scavenging carcasses. These creatures lived during the Paleozoic period around 250 million years ago to 68 million years ago, making them a significant part of the Mesozoic biodiversity.
