These collections bring related Dinozavrikus guides together by subject. Browse dinosaur groups, marine reptiles, fossils, palaeontology, evolution and geological time. The directory links to collections with English pages; more sections will be added as the wider site is translated.
Explore the collection
Cenozoic Era
Explore the Cenozoic Era from 66 million years ago to today: the Palaeogene, Neogene and Quaternary, mammal and bird radiations, cooling and humans.
Mesozoic Era
Explore the Mesozoic Era from 251.902 to 66 million years ago: Triassic recovery, Jurassic ecosystems, Cretaceous change and dinosaur evolution.
Palaeozoic Era
Explore the Palaeozoic Era from the Cambrian to the Permian: six periods, changing seas, the colonisation of land and the end-Permian crisis.
Animal evolution across changing worlds
Follow animal evolution through fossil lineages, changing anatomy, ecological evidence and the limits of reconstructing extinct lives.
The Cretaceous Period: dinosaurs, fossils and a changing world
Explore the Cretaceous through dinosaur fossils, ancient environments, changing continents and the geological boundary that ended the period.
The world of dinosaurs: fossils, evolution and ecosystems
Explore dinosaur groups, anatomy, habitats and fossil evidence through guides to how these animals lived and diversified.
Pterosaurs and the evolution of powered flight
Explore pterosaur fossils, wing anatomy, flight, feeding and diversity while keeping these flying reptiles distinct from dinosaurs.
Fossils and the evidence preserved in rock
Explore body fossils, footprints, burrows and other traces, and learn what each kind of evidence can reveal about ancient life.
Human evolution and the evidence for our past
Explore human evolution through fossil hominins, archaeology, ancient environments and the evidence used to reconstruct how people lived.
Marine reptiles of the Mesozoic seas
Explore ichthyosaurs, plesiosaurs, mosasaurs and other marine reptiles through their fossils, anatomy and ancient ocean habitats.
Ornithopods: from early forms to duck-billed dinosaurs
Explore ornithopod dinosaurs through fossils of early forms, iguanodontians and hadrosaurids, with attention to changing classification.
Palaeontologists and the work behind fossil discoveries
Meet palaeontologists and explore how fieldwork, collections and scientific analysis turn fossil finds into evidence about ancient life.
Small dinosaurs in a world of giants
Meet small-bodied dinosaurs and examine how fossils reveal adult size, growth, ecology and the limits of body-mass estimates.

Frequently asked questions
What can I find in the topic collections?
The collections group English guides by subject, including dinosaurs, marine reptiles, fossils, palaeontology, evolution and geological time.
Are all Dinozavrikus sections available in English?
No. This directory lists topic collections that currently have English pages. Further sections will appear as the site translation progresses.
How are the collections organised?
Each collection groups related guides around a subject. A topic page can link to articles and profiles that are already available in English.
Are pterosaurs and marine reptiles dinosaurs?
No. Pterosaurs, ichthyosaurs, plesiosaurs and mosasaurs were distinct reptile groups outside Dinosauria, although they lived during some of the same geological periods.
