The heaviest predatory dinosaurs. Theropods Top 10

The heaviest Theropods – TOP10

Dinosaurs have always been a source of fascination for people of all ages. These giant creatures once roamed the Earth and now captivate our imagination with their sheer size and power. Among the dinosaurs, theropods were a group of carnivorous dinosaurs that stood out for their hunting abilities and massive size.

These predators ruled the land and dominated the food chain, with some species reaching lengths of up to 14 meters and weighing over 9 tons. In this article, we will take a closer look at the top 10 heaviest theropod dinosaurs that ever lived. From the mighty Tyrannosaurus Rex to the lesser-known Spinosaurus, we will delve into the anatomy, hunting habits, and characteristics of these incredible beasts. So buckle up and get ready to meet the largest and most intimidating predatory dinosaurs that ever existed.

Since the original version of our summary was published, scientific studies have reviewed the weight data for theropods. It turns out that the earlier vision of a Spinosaurus was not the truth, and that it was not the heaviest predatory dinosaur. So in 2020 we updated the data, which we present in a table at the end of the article. This is the most comprehensive list of theropods in the world.

Dinosaur Database

We are a group of biologists and paleontologists, creating articles and popular science publications that present the world of animals, plants and introduce the nuances of paleontology in an accessible way for readers. All our articles are based on the most valuable sources and scientific works. Articles are also based on our own research and paleontological excavations. Our Databases: The largest Dinosaur Database: and The largest Pterosaur Database:


  1. Redakcjo, Ibrahim oszacowal objetosc FSAC KK 11888 na 3864 l, a dlugosc na 10.37 (in natural pose) i na 10.93 m (in maximum length) Spinozaur wg Franoysa ma gestosc 0.995
    0.995*3864 l=3845 kg.
    MSNM V4047 mial czaszke o dlugosci 147.7 cm, a Neotyp mial czaszke o dlugosci 112 cm
    Wiec MSNM V4047 wazyl 8818 kg.
    A jego dlugosc to 13.68 i 14.41 m

    Holotyp mial czaszke o dlugosci 113 cm i 7 kreg grzbietowy o dlugosci centrum 19 cm (vs 17 cm u FSAC KK 11888)
    Wiec mial 10.61 i 11.18 m, a waga to 4120 kg.

    Zuchwa BMNH R 16421 ma 69 cm, a czesc uzebiona zuchwy holotypu ma 51.7 cm.
    Moja szacunkowa dlugosc tego osobnika to 14.16 i 14.92 m, a moja szaunkowa Waga to 9793 kg
    Wiec mam dowody, ze Spinozaur osiagal wage 10 t

    1. Ciekawostka jest, ze fragment zuchwy pod nazwa BMNH R 16421 ma 17 zebodolow, a holotyp tylko 15

      1. Może lepiej, abyśmy założyli dla Ciebie blog, abyś mógł przedstawiać takie analizy? To będzie znacznie lepsze i czytelniejsze dla wielu odbiorców.
