<thinking>Let's approach this step-by-step:
We should reason through this methodically (CoT):

Step 1: What is the challenge instructing me to do?
Identify the occurrence of character "r" in the text "Icthyosaurus"

Step 2: Dissect the word.
I-C-T-H-Y-I-S-A-U-R-U-M


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Icthyosaurus", not "icthyisaurum". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. I
2. C
3. T
4. H
5. Y
6. O
7. S
8. A
9. U
10. R
11. U
12. S

Step 5: Pinpoint the positions of the letter "r".
The letter "r" appears at the 10th position in the word.

Step 6: Count the letters.
A: 1, Y: 1, T: 1, R: 1, U: 2, S: 2, I: 1, H: 1, O: 1, C: 1

Step 7: Evaluate the letters we quantified.
The specified letter was "r" and there are 1 altogether.

To conclude:
The letter "r" is present 1 instance in "Icthyosaurus", at the 10th position.</thinking>
