Dinosaur scale

dinosaur scale

If you click on this link you will find out how to make scale dinosaurs for lego men (4cm) or other such things. The dinosaurs used are either from North america or Britain. Using my formula you can do the same for other dinosaurs.

2 new ceratopsians found, one of which is weirder than Einiosaurus


 Some new ceratopsians have been found in utah. Big deal you may say. But they seam to have lived on a long island (see picture) which no longer exists. It was called laramidia which was separated from the rest of the USA by a wide, shallow sea. They were called Utahceratops (6metres) and smaller Kosmoceratops (4.5 metres) , the later being the weird one. Unlike triceratops, its horns seem to be mostly used for display. Many ceratopsians have been found on the ex-island. It is strange that so many dinosaurs could live in the same palce. One theory is that they had  slower metabolisms so they did not need as much food or space.

Baby giant ground sloth in my back garden!

I like things big. So it is not suprising that I made a ground sloth in my garden using snow. Bigger than a snowman (though smaller than an adult ground sloth) this is one huge baby! 

If you have a giant snow beast you would like to show the world please post a reply and I will put it up.

Ceratopsian madness!

In dinosaur terms, the ceratopsians were fairly recent. Lately some new discoveries have changed the way we look at them forever. But first I must bust an annoying myth which is going round the net.

Triceratops does not exist!

 What on earth is this! Some are saying it is just a baby torosaurus. This is silly. Firstly,  like many ceratopsians, triceratops had small spikes on his frill. Unlike many ceratopsians, he had a solid frill. Torosaurus hade no spikes and holes in his frill. Also, triceratops was bigger than torosaurus. An unlikely baby! If it was a baby to one dino it would have to be eotriceratops.


Eotriceratops was really just like a huge triceratops. He was so huge the large therapod that lived with him (albertosaurus) was smaller than him! His head was so big that he could scoop up an albertosaurus and toss it away. He was 13 tonnes which is heavier than an average diplodocus. It was the ultimate power house of dinosaurs.


What is so special about this relative of badgeceratops? Simply because it lives in Europe. It is the missing link between Bagaceratops from Asia and montanoceratops from North America. Like all ceratopsians it walked on 4 legs (with the exception of yin long and psittacosaurus) and had a mixed diet of twigs, bushes and carion.Now here is some food for thought. When the first triceratops was found it was thought that it was a bison. Then we found out it was a dinosaur a bit like a rhino. Know we know that it ate like a pig, was as strong as an elephant and most of all fought like a bison. So maybe we should look back at the ancient mistakes made by paleontologists and think “Were they trying to tell us something?”

More prehistoric colour

This time the colourful animal in question is not a dinosaur but a penguin. When it was discovered we had the technology to find colour, straight away the tests were done. Suprisingly the penguin, instead of being black and white was grey and red! This shows that penguins used to have red bellies but over time they evolved white bellies. On the other hand the change in the back is not as surprising as grey is just light black.

The beast is known as the water king penguin or Inkayacu paracasensis and lived about thirty-six million years ago. Not only was it strangely coloured it was also giant, about 1.5 metres tall.

Dimetrodon vs edaphosaurus

In the BBC’s TV program, “walking with monsters” a dimetrodon was dipicted catching and killing a baby edaphosaurus (how dare it!) After reading a book about dinosaur myths, I came apon a part talking about the successfulness of dimetrodon. If you look at its predator/prey percentages you would see that 25% of the animals in dimetrodons’ area were dimetrodons! The other 75% were its dinner! This percentage is equal to that of a spider.

The question is “who were dimetrodon’s prey”? Baby animals were easy meat as the parents were not as protective as the parents of elephants, tigers, hippos ect, more like zebras who are useless at it or komodo dragons who don’t give a toss about their children and, when peckish, might eat them. It is true that dimetrodon might have been a cannibal. On the other hand the edaph in the video was an only child and, as you know with animals, the smaller the amount of children the more protective the mum.

The next thing you have to think about is where the dimetrodon was living. If it lived on the shore of a lake, its main prey was the fish-eating reptile ophiacodon. This beast was nearly the size of dimetro at 3metres long. In these areas dimetro was at its commonest. Then there was the small ponds and swamp plains. Here the smaller amphibian eryops lived. At only 2metres it was not as much of a meal as ophiac so dimetro was less common here. Finally, there was the dry flood plains where the 3metre long diadectes lived.

You might now say “where did dimetro do badly”. The answer is the geraldine bone bed in Texas. The only possible prey was an eel-like amphibian called archeria and, you guessed it, EDAPHOSAURUS! This is probably because archeria could swim away and edaphosaurus, who was the the same size as dimetrodon, 3.5metres, had a spine to scare dimetrodon off, although dimetro had one of its own, and probably lived in herds.

The conclusion: dimetrodon did not eat edaphosaurus!

The picture is of dimetrodon’s dinner. Notice that there are no edaphosaurs!

Styracosaurus gone bad


styracosaurus-gone-badTo the left is a very confusing picture of  a styracosaurus EATING AN ALBERTOSAURUS! This amazing picture by Mark Witton is not as crazy as it seems. He says that like hippos, camels and pigs, the ceratopsians may have included some carrion in there diet. This makes sense as the jaws and teeth were made for chopping things like hard twigs. I think they might have also eaten roots, digging them up with there horns like rhinos.

This also adds an ending to my t-rex vs triceratops story. This is the story: T-rex atacks triceratops because it is starving. Triceratops fights back and kills t-rex. Triceratops eats t-rex.

The End.

P.S. Nature always suprises you doesn’t it.

Anchiornis and Sinosauropteryx, dinosaurs in true colour.

I know, it has been a famous saying in both books and films alike, “we don’t know what colours dinosaurs were.” Well now that would be lieing in two cases. True in that we don’t know what colour T-rex or Triceratops were (but if I find out I will let you know.)
The two dinosaurs I am talking about are not famous (true to edaphosaurus.com’s main aim in life, trying to give fame to the un-famous.) Their names are Anchiornis and Sinosauropteryx.
Anchiornis was mainly black, with white on its wings, leg feathers and feathers around its tail/bottom area. It also had a large red crest on its head. Knowing how big it was (smaller than Micro-raptor, allegedly the smallest dinosaur) and weighing only 110 grams, it probably ate insects and other ugly bugs.
On the other hand, turkey sized Sinosauropteryx ate slightly larger things such as small mammals and lizards. Like Anchiornis, it lived in the late jurrassic era. It had a mohecan style crest on its head and a ring tail lemur style tail but this time orange and white.
If I find any more prehistoric animals which we know the colour of I will inform you. So stay tuned!
