Dinosaurs Were Taller than Thought!

Jurassic Park’s velociraptors were awe fascinating in intelligence( Remember the social behaviour of velociraptors was quite akin to primitive human civilization). I don’t know if some of them had survived the catastrophes and developed an advanced civilization that flourished during post cretaceous era(though it’s unlikely that they survived the catastrophe if we are going to consider the research by Victor Babbitt in which he proposed that SO2 unleashed after comet impact might have destroyed the eggs of Dinosaurs.).

New research showcases that Dinosaurs were taller than thought. Some dinosaurs may have been at least 10% taller than previously thought, U.S. palaeontologists said in a study that found the creatures had large amounts of cartilage.The dinosaurs had thick layers of cartilage in their joints that may have added more than 30 centimetres to their height, according to researchers at the University of Missouri (MU) and Ohio University, who said this may have changed their speed and posture.

Our study of the limbs of modern-day relatives of dinosaurs shows that dinosaurs were significantly taller than original estimates.


[Image Details: A three horned dinosaur estimated to have reached about 7.9 to 9.0m (26.0–29.5 ft) in length, 2.9 to 3.0 m (9.5–9.8 ft) in height, and 6.1–12.0 tonnes (13,000–26,000lbs) in weight. The most distinctive feature is their large skull, among the largest of all land animals. It could grow to be over 2 m (7 ft) in length, and could reach almost a third of the length of the entire animal.]
She explained that many dinosaurs’ long bones, such as the femur or tibia, lack major articulations and have rounded ends with rough surfaces. This indicated that very thick cartilages formed these structures, and therefore the joints themselves, and would have added significant height to certain dinosaurs. In contrast, mammal bones have small protrusions at their ends that help them connect with other bones at a joint. The bones are then linked with a very thin layer of cartilage.

Using cartilage to measure height

The study, which was published in PLoS-ONE, shed further light on how reptiles and mammals such as humans build their joints with different amounts of cartilage and bone.The researchers compared articulations of ostriches and alligators – the closest living relatives to dinosaurs – to fossilised limbs of dinosaurs like Tyrannosaurus rex and Triceratops.

They found that alligators’ and ostriches’ limbs included six to 10% cartilage. By applying a ‘cartilage correction factor,’ Holliday, a researcher, found that many theropod dinosaurs, such as Tyrannosaurus, were only modestly taller, while ornthischian and sauropod dinosaurs like Triceratops and Brachiosaurus, may have been 10% taller or more.

Brachiosaurus, which was previously thought to be 13 metres tall, may actually have been more than a foot taller with the additional joint cartilages, according to the researchers.

This study is significant because it shows that bones can’t always speak for themselves. To understand how dinosaurs moved, we need to analyse the bones as they were inside their bodies, including their cartilage. Dinosaurs bones mounted in museums in fact do not accurately reflect the creatures’ height when they were alive because the cartilage caps and other soft tissues were lost.

A simple conclusion can be withdrawn by now that dinosaurs were more furious that we could imagine.
