Ostafrikasaurus by Hyrotrioskjan Ostafrikasaurus by Hyrotrioskjan
The newest member of the Spinosauridae is one their oldest.

We have just one isolated tooth from the Tendaguru, but this tooth tells us that it was a very primitive member of the clade. It's thicker and have larger denticles than the the teeth of Barynoyx (his next relative) so I decided to give him a look somewhere between Megalosaurus and Baryonyx.

This drawing is highly speculative so better don't use it as reference.

It's amazing how the paleontologist who discovered this dinosaur could distinguish it from other members of it's genus by a simple tooth.

Its COOL!!! Looks like Dinocroc on syfy XD
But I think the megalosaur like primitive spinosaur is very realistic.

It's an amazing drawing, and the perspective is amazing. However, I have found one fault, but it's not even a real fault. You've put feathers on a fully mature Baryonyx, so wouldn't a more primitive member of the group also have feathers? It just doesn't make sense to leave them off when you've given them to a derived spinosaurid.

There are two reasons for that difference =)
1. I think that every spinosaur had proto-feathers in it's youth, but that doesn't mean that every species have feathers as an adult.
2. Baryonyx lived in the north, maybe even in a moderate climate zone where it was a bit colder during the winter.

It is an awesome work, very beautiful, but for feathers... why would a Velociraptor have feathers in Mongolia?

:iconhyrotrioskjan:
Hyrotrioskjan Featured By Owner Mar 4, 2014  Professional General Artist
Desert birds have also feathers =)
Feathers are not only for warming but also for cooling (because of multiple reasons)
In addition dromaeosaurs like Velociraptor used their long tail- and armfeathers as display structures and to improve their running style, how some ground birds do it today

So......was it transitional between megalosaurid ancestors and other spinosaurs or just a spinosaur?

We don't know, only one tooth is too less to say more about it's morphology and phylogeny.

Ah, a pity, It'll b nice to see a real ancestral spinosaur....maybe Ostafrikasaurus is more derived even than that if everyone's putting it as a member of Spinosauridae...

Hi, I am Teddy. Once you read this you
cannot get out. Finish reading this
until it is done! As I said, I am
Teddy. I am 7 years old. I have no eyes
and blood all over my face. I am dead.
If you don't send this to at least 12
people I will come to your house at
midnight and I'll hide under your bed.
When you're asleep, I'll kill you.
Don't believe me?"no"
Case 1:
Patty Buckles
Got this e-mail. She doesn't believe
in chain letters. Well, Foolish Patty.
She was sleeping when her TV started
flickering on and off. Now she's not
with us anymore. Ha ha patty, Ha ha!
You don't want to be like Patty, do
you?
Case 2:
George M. Simon
Hates chain mail, but he didn't want
to die that night. He sent it to 4
people. Not good enough George. Now,
George is in a coma, we don't know if
he'll ever wake up. Ha ha George, Ha
ha! Now, do you want to be like George?
Case 3:
Valarie Tyler
She got this letter. Another chain
letter she thought. Only had 7 people
to
send to. Well, That night when she was
having a shower she saw bloody Mary
in the mirror. It was the BIGGEST
fright of her life. Valarie is scarred
for
life.
Case 4:
Derek Minse
This is the final case I'll tell you
about. Well, Derek was a smart person.
He sent it to 12 people. Later that
day, he found a $100.00 bill on the
ground. He was premoted to head
officer at his job and his girlfriend
said
yes to his purposal. Now, Katie and
him are living happily ever after.The
have 2 beautiful children.
Send this to at least 12 people or
you'll face the consequences.
0 people- You will die tonight
1-6 people- you will be injured
7-11 people- you will get the biggest
fright of your life
12 and over- you are safe and will
have good fortune
ally scared.
