Pterodactyl comes from the Greek meaning "winged finger". Ptero is the Greek for winged, so it comes from the Greek. In Greek, the "p" isn't silent.
(*excluding the words that begin with PH and have an F sound : pharmacy, phenol, photo) There is a silent P in pneumonia, ptomaine, pteradactyl, raspberry, receipt, and PS words such as psalm, psychology, and pseudonym.

The letter P is silent in the word psychology.
Phthisic is pronounced tiz-ik so the ph and the second h are silent.
P....The letter P is silent as it is usually not pronounced.

The silent letter in the word ptarmigan is 'p'.
The P is silent.
The silent letter in raspberry is the "p."
Some examples of English words with a silent P are pneumonia, pneumatic, psychic and psychiatrist.
In the word "psychology," the "P" is silent because it is derived from the Greek word "psyche." The English language borrowed this word along with its silent "P." In words like "pneumonia" or "psychiatry," the "P" is silent as well, following the same etymological pattern.
In words starting with pt-, the p is silent (as pterygium). In words starting with PS-, also the p is silent (psycho-<whatever> or pseudo-<whatever>). In phthisis the pH is silent. I seem to be stuck on the letter "p" right now, but I am sure there are words with other silent letters.
