3 Dinosaurs to Color

 Welcome to my Free Coloring Pages blog!   

Today there are 3 drawings of dinosaurs for you to print and color. 

Parasaurolophus Chick Hatching

Parasaurolophus was a fairly large Hadrosaur.  That means it was a duck-billed dinosaur.  It was 36 feet or about 14 meters long.  Parasaurolophus was unique in that it had a long, curved, hollow crest.  It appears that it may have used the crest like a trombone to amplify its calls.  Females seem to have had smaller crests than males.  So as a result, males had deeper voices than females...  (kind of like humans). 

In this drawing the newly hatched Parasurolphus chick is looking around after the top part of the shell fell off.  The nest has fern or cycad leaves... with the eggs resting in the leaves.  There IS some evidence that dinosaurs, like birds, lined their nests with leaves and maybe branches.  They may have even covered the eggs with plant matter to keep the eggs warm. 


Brachiosaurus Sub-Adult feeding on a Cycad Tree

This is a rather quick and simple drawing that I did for my grandson during church.  (My grandson is only 3.) Drawing helps me keep awake and alert during church meetings.  In fact, being someone who has ADHD I find that drawing helps me focus really well.  It is my ADHD medication... with no side effects.  Of course, drawing also helps me relax and unwind as well.  

This drawing is of a young Brachiosaurus.  Brachiosuars were some of the biggest dinosaurs ever!  The largest known Brachiosuar was Sauroposeidon and it was around 60 feet tall.  That is 18 meters!  It also weighed an estimated 66 tons.  The young Brachiosaurus in this drawing is a sub-adult.  It is feeding on a cycad tree.  There seems to be some evidence that the newly hatched Sauropood babies were on their own until they grew larger enough to join the herd.  When they joined the herd they would have been around the weight of a full-grown African elephant... 18,000 lbs or about 8000 kg.  Of course, due to the long neck on Brachiosurs... the sub-adult Brachiosaurs would have been twice as tall as an African Elephant.  So this sub-adult Brachiosaurus would have been around 28 feet tall... or about 5 meters tall. 





T. rex Chicks hatching

There is some thought that T. rex may have been heavier than previously estimated.  In fact, some paleontologists think that a full-sized T. rex may have weighed as much as the above sub-adult Brachiosaurus. . . that is 18,000 lbs or 8000 kg.  Tyrannosaurs were Theropods.  Theropod eggs have been found in Portugul and it seems clear that the young would have needed parental care.  So as huge and fierce a killer as it was, T. rex was almost certainly a good parent.  There is also evidence that Tyrannosaurs lived in packs and probably mated for life, like birds of prey tend to do.  So both parents were probably good parents.  Notice that the T. rex nest is also lined with fern or cycad leaves.  

By the way, this drawing was also done for my grandson during church.  He wanted me to add volcanic bombs erupting from the volcano and an "asteroid."  That is what he called the meteor.  To be clear... a rock in space IS an asteroid.  When it enters the atmosphere and starts to burn up it is a meteor.  IF the meteor hits a planet it is a meteorite.  I always remember that it hit "RIGHT" on the planet so it is called a meteorite.   This meteorite in the drawing CAN'T be the ONE... the one that wiped out the dinosaurs because it appears that Parasaurolophus disappears from the fossil record around 71 million years ago.  So Parasaurolphus evolved into other forms or types of Hadrosaurs and did not survive as a species to the end of the Cretaceous Period or 65 million years ago... when the huge meteorite hit the Yucatan peninsula and killed off all the dinos except for avian dinosaurs or birds.  


NOTE:  These drawings, in printable form, will soon all be found by clicking on the button labeled "Paleontology."  Then scroll down to find the correct drawing you want to print and color.  HOWEVER... I need to run some errands so the printable versions of the drawings will be posted a bit later tonight.  Sorry for the inconvenience.
