Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The largest of these animals were Paraceratheriidae and Proboscidea. [20] Other taxa included Brontotheriidae. [21] The Sirenia, aquatic megaherbivores, such as Dugongidae, Protosirenidae, and Prorastomidae were present in the Eocene. [22] Megaherbivores inhabited every major landmass in the Cenozoic and Pleistocene before the arrival of humans ...
The plant-eating dicynodont Lisowicia bojani is the largest-known of all non-mammalian synapsids, at about 4.5 m (15 ft) long, 2.6 m (8 ft 6 in) tall, and 9,000 kg (20,000 lb) in body mass. [11] [12] [13] However, in 2019 its weight was later more reliably estimated by modelling its mass from the estimated total volume of its body. These ...
Parasaurolophus, a crested hadrosaur.. Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores.The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.
Coronacollina acula is a multicellular organism from the Ediacaran period resembling the Cambrian 'sponge' Choia.The organism comprised a raised, tri-radially-symmetrical central mound with a central depression and resistant spicules (up to four in articulated fossils), which were resistant — either chitinous or biomineralized — and grew to be 37 cm long.
A fossil reveals how a now-extinct species of dugong was swimming in the sea about 15 million years ago when it was preyed upon by a crocodile and a tiger shark.
Coprolites (fossilized droppings) of some Late Cretaceous hadrosaurs show that the animals sometimes deliberately ate rotting wood. Wood itself is not nutritious, but decomposing wood would have contained fungi, decomposed wood material and detritus-eating invertebrates, all of which would have been nutritious. [7]
