Walking Dinosaurs: The Giants of the Land (continued)





1. Herbivorous Walking Dinosaurs (Plant-Eaters)

Many dinosaurs that walked on land were herbivores, meaning they fed on plants. These dinosaurs developed special features to help them survive, such as long necks, powerful legs, and large bodies. Some of the most famous plant-eating dinosaurs include:

  • Brachiosaurus: A massive dinosaur with a long neck, allowing it to eat leaves from tall trees. It walked on four legs, with its front legs longer than the back ones.

  • Stegosaurus: Known for its large plates along its back and spiked tail, it walked on four legs and fed on low-growing plants.

  • Triceratops: A horned dinosaur with a large frill protecting its neck. It had a strong beak to bite through tough plants and walked steadily on all four legs.

  • Iguanodon: A dinosaur that could walk on both two and four legs, with thumb spikes used for defence.

These dinosaurs often lived in herds for protection and may have migrated in search of food and water.

2. Carnivorous Walking Dinosaurs (Meat-Eaters)

Other walking dinosaurs were carnivores, hunting or scavenging other animals for food. They were usually lighter, faster, and had sharp teeth and claws. Some of the most well-known include:

  • Tyrannosaurus rex (T. Rex): One of the most famous predators, it walked on two powerful legs, had a massive skull, and tiny arms. Despite its size, it could run quickly for short distances.

  • Velociraptor: A smaller, agile predator with sharp claws and keen intelligence. It likely hunted in packs and walked or ran on two legs.

  • Allosaurus: A strong predator from the Jurassic period, it had large claws and teeth for tearing flesh, and it walked upright on two legs.

These predators played a key role in balancing the ecosystem by controlling the populations of herbivores.

3. How Did Walking Dinosaurs Move?

Walking dinosaurs had different types of movement:

  • Bipedal dinosaurs walked on two legs. These were usually faster and more agile, such as T. rex and Velociraptor.

  • Quadrupedal dinosaurs walked on four legs. These included large, heavy herbivores like Apatosaurus and Ankylosaurs.

  • Some dinosaurs, like Iguanodon, could switch between two-legged and four-legged movement depending on speed or activity.

Palaeontologists study fossilized footprints (trackways) to learn more about how these animals walked, how fast they moved, and whether they travelled in groups.

4. Defence and Adaptation

Walking dinosaurs developed many strategies to survive:

  • Armoured skin: Like in Ankylosaurs, with bony plates for protection.

  • Speed and agility: To escape predators, as seen in smaller bipedal herbivores.

  • Group behaviour: Herding and group migration helped protect them from danger.

  • Camouflage: Skin patterns might have helped them blend into their environment.

5. Extinction and Legacy

All non-avian dinosaurs, including the walking ones, went extinct about 66 million years ago, most likely due to a massive asteroid impact that changed Earth’s climate. However, many scientists believe that modern birds evolved from small, feathered walking dinosaurs, especially from a group called theropods.

Today, their fossils continue to teach us about evolution, biology, and the history of life on Earth.

Conclusion

Walking dinosaurs were among the most incredible creatures to ever roam the planet. From the towering herbivores that grazed in forests to the sharp-toothed hunters that ruled the plains, these animals shaped prehistoric ecosystems for millions of years. Thanks to fossils, footprints, and modern science, we continue to uncover their secrets — step by step.

Reptiles: Ancient Amniotes Shaping Today’s Biodiversity

صورة
  Reptiles are ectothermic, scaly-skinned tetrapods that reproduce with amniotic eggs or (in some lineages) live birth. They first appeared ≈ 310 million years ago and became the dominant terrestrial vertebrates through much of the Mesozoic Era, giving rise to numerous extinct lineages—including dinosaurs, of which modern birds are the surviving branch. Today, four living orders remain and together comprise ≈ 12,440 described species —more than double the number of mammals—making Reptilia the second-largest vertebrate class after fishes. reptile-database.org Modern Diversity in Context Traditional classification: Testudines (turtles), Crocodylia (crocodiles & alligators), Squamata (lizards, snakes, amphisbaenians), Rhynchocephalia (tuataras). Wikipedia Cladistic view: Birds nest within “reptiles,” rendering the classical class Reptilia paraphyletic. Wikipedia Species richness: Squamates account for > 95 % of extant reptile species; other orders are relictual. ...

Abū al-Ṭayyib al-Mutanabbī (915 – 965 CE): An English Overview

صورة
  1 | Life and Historical Context Al-Mutanabbī was born in 915 CE in Kūfa (present-day Iraq) to a modest family that nevertheless claimed noble South-Arabian descent. Brilliant from childhood, he mastered classical Arabic and quickly attracted attention for his precocious verse. During his teens he lived among Bedouin tribes influenced by the Qarmatian movement; in 932 he was briefly hailed as a would-be prophet (hence the sobriquet al-Mutanabbī , “the one who claimed prophethood”) before being imprisoned by the Ikhshīdids. After his release he began a dazzling career as a court panegyrist, serving first the Ḥamdānid emir Sayf al-Dawla in Aleppo (948 – 957) , then the Ikhshīdid vizier Abū Misk Kāfūr in Cairo (960 – 962) . He died in 965 near Dayr al-ʿĀqūl on the road to Baghdad when highwaymen—whom he had once satirised—recognised and killed him. britannica.com arabamerica.com 2 | Poetic Style and Aesthetic Innovations Al-Mutanabbī’s diwān (about 326 surviving poems) is reno...
