Sowthistle?

I've got two seemingly different yellow flowers in front of the house. They kinda both fit the descriptions for annual and perennial sow thistle. There is some that are larger with 1 inch wide flowers, and other more scraggly ones with branching stalks of 1/4 inch flowers. The big ones went to seed already and made a puffball with long skinny rice-like seeds with the hair-like tuft attached to it. The smaller ones just keep flowering and I am not seeing a puff yet from them.

So do either of these look like either sow thistle? What do you all think?

Hawkweed on right???[my best guess, but maybe some more astute readers will correct me....

The one on the left looks like salsify to me (Tragopogon dubius). Based on the shape of the one on the right, I'd guess it's a close relative to salsify (if not also salsify). Hawkweed is also a possibility.

My first thought was that the one on the left is False Dandelion.  According to this article there are several plants with that name.

   Hypochaeris radicata, also known as catsear, the plant most commonly referred to as false dandelion
   Hypochaeris other catsears related to H. radicata

   Crepis, also known as hawksbeards
   Hieracium, also known as hawkweeds
   Leontodon, also known as hawkbits
   Nothocalais
   Pyrrhopappus
   Scorzoneroides, also known as hawksbits

According to this article [below] there are two sow thistles.
