Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus and ...
English: A comparison of several size estimates for Deinosuchus, a giant Late Cretaceous crocodilian. The largest credible specimen of modern C. porosus (saltwater crocodile) is also included in the diagram for comparison, as is an average height human. Full citation information: Colbert, Edwin H; Bird, Roland T. (1954).
For comparison, the wandering albatross has the largest wingspan of living birds at up to 3.5 m (11 ft) but usually weighs less than 12 kilograms (26 lb). This indicates that the largest pterosaurs may have had higher wing loadings than modern birds (depending on wing profile ) and this has implications for the manner in which pterosaur flight ...
Size comparison of selected giant sauropod dinosaurs (from left to right): Supersaurus, Argentinosaurus, Diplodocus, Mamenchisaurus, and Sauroposeidon. A mega-sauropod, Maraapunisaurus fragillimus (previously known as Amphicoelias fragillimus), is a contender for the largest-known dinosaur in history.

The UK's biggest ever dinosaur trackway site has been discovered in a quarry in Oxfordshire. About 200 huge footprints, which were made 166 million years ago, criss-cross the limestone floor.

Size comparison of a human to Q. northropi (green) and Q. lawsoni (blue) In 1975, Douglas Lawson compared the wing bones of Quetzalcoatlus northropi 's holotype to equivalent elements in Dsungaripterus and Pteranodon , and suggested that it represented an individual with a wingspan of around 15.5 m (51 ft), though presented alternative ...
