HI I ALSO LIKE DINOSAURS

Hi!! That’s great to hear!!!

I’m working on some more posts!!

Introduction to dinosaurs and bones!

Vocabulary:

Paleontology: the study of all prehistoric life.

Fossil: any preserved evidence left behind by a prehistoric organism.

Adaptations: traits that have been evolved because they serve specific purposes.

Content:

Dinosaurs came in all sorts of shapes and sizes! They weren’t all huge, some of them were probably less than a meter long when fully grown (like the Microraptor, or the Fruitadens)!! And, contrary to popular media (The Jurassic Park series), the Velociraptor was actually about the size of a dog, or a turkey; give or take.

A good example of an adaptation would be bones! Bones help all animals survive by serving four major functions:

They passively resist the force of gravity and maintain an animal's form!

Bones provide a rigid framework for muscle attachment!

As much as they provide protection internally, they could easily be fantastic weapons (think horns, and other things like that).

They act as HUGE mineral reserves!

The Skulls and Jaws!

Vocabulary:

Vertebrates: animals with two kinds of special skeletal adaptations: the skull and vertebrae.

Vertebrae: structures primarily made out of bone and/or cartilage that surround a portion of the spinal nerve cord.

Vertebral column: a series of interlocking vertebrae.

Brain case: a hollow chamber formed by multiple skull bones that houses the brain!

Fenestrae: Latin for “windows.”

Content:

Skulls are not singular bones! The skull is made up of many bones that are tightly locked together. The skull itself can give greater insights about a dinosaur's life than really any other bone(s)!

The upper and lower jaws may contain teeth and/or include a beak, and these things are critical for paleontologists to be able to interpret what the mighty beast(s) were adapted to eat!

The rear portion of the skull includes the brain case. There are many small openings in the brain case that allow nerves to connect to the brain. Which is very important, and is still a present adaptation today. The size and shape of the brain case can indicate the size and/or shape of the brain it housed, and, therefore, provides us with clues to the dinosaur's mental capabilities!

Dinosaur skulls also have multiple pairs of large openings! These included the:

Nares: the openings for the nostrils.

Orbits: the openings for the eyes.

In some modern animals, like turtles, there are no other skull openings. This is another example of animals evolving and adapting to their environments! Dinosaurs had a few more openings in their skulls, which were called:

Fenestrae!

Behind each orbit there were two fenestrae:

On the lateral sides of the skull, there were the two laterotemporal fenestrae.

On the top of the skull, there were the two supratemporal fenestrae.

Both pairs were present in the skull to make room for large jaw muscles!

Between each orbit and naris, dinosaurs also had a third pair of fenestrae! These were called the antorbital fenestrae. Though, the exact function of this is unclear; I like to think that in some dinosaurs it helped warm the air that they breathed, and in others it simply made the skull a little bit lighter.

Hi Wil!! How’re you doing today?? Good luck with your schooling; because I know for a fact that this profession you’re going into will always be in high demand(because people like me exist that don’t know how to work/fix/make their electrical appliances)!!

Anyways, if you need anything feel free to message me!! Have a great day, stay safe; and do your best! Cause you got this!!

Hi! I'm Willow!

I'm trying out a study blog for the first time here! I'm also just new to tumblr, so I'm not %100 sure what I am doing XD

I go by Wil or Willow (Wil is spelt with a singular L) and I use they/them pronouns, I live in Washington, USA, and I'm 18! I'll be studying Electrical Engineering, and I'm going to be a freshman in college in mid August.

I love working on videogames and bookbinding in my spare time, but I've recently picked up knitting. I am eternally fascinated by outdated technology (just got a cd, cassette, and radio player from goodwill the other day). My parents think I'm crazy because this was the stuff they grew up with but its one of my special interests so they can't do anything about it.

I'm making this studyblr because I want a public means to keep myself motivated next year. I hope to do fantastic things over the next four years!

thank you to @myhoneststudyblr, @studyquill, and @eintsein for creating their "how to create a studyblr" posts! Probably would be too scared to start without these as resources!

Hiiiiii!!! Just wanted to let you know that I did a happy dance when I saw your art!! Lovely color choices—lovely little details on the neck—lovely cloud in the background—

Lovely art piece!

Have a great day!!

Hi! I’m Alex!

And I love dinosaurs! I’ve always loved dinosaurs, though I never really got the chance to talk about them because I always got way too excited and info-dumped on the other person… but!! Now I have a tumblr; and I’ll be posting my notes and things to this little void!

Also! Here are some fun facts about my page:

I am 20 years old! Though, I will not be posting any NSFW content, I do want the younger users to know that I’m a little bit old!

Any pronouns are fine! And, if you think of any neo-pronouns for me; let me know! I’d love to hear them!

This is a SAFE space for the folks of the LGBTQ+ community, POC, any sort of victim, what have you!

With that being said, the is NOT a safe space for:

the DJT CULT, racists, radical feminists, ableist, Blue lives matter, and anyone else who fall into any sort of similar category! I would also use the block button freely. <3

If you need an older sibling to vent to, message me! If you have a question, drop it in the 🦖!! If you’re embarrassed to ask something(which you really shouldn’t be), I’m pretty sure I have anonymous asks on too!!

Have a lovely day!! Stay safe!!
