What kind of weed?

[justleesa]

Ok this is the first time that I have had the chance to do some landscaping. We rototilled and seeded the front yard a few weeks ago and now have some nice grass growing....and some weeds. This kind of weed wasn't there before, so I am almost thinking that they came with the grass seeds ...they are fat and juicy leaves and stems and if I don't keep up with them they will get yellow flowers. I can't used the weed kill stuff till I've mowed the lawn 3 times (one more to go) but I would like to know what kind of weed it is....anyone?

Thanks for the heads up! Are there different kinds of buttercup? the flower on this appears directly on the crown of the leaves - buttercups I remember (only remember the flower, not the leaves) sends up an extra shoot, no? Wouldn't be the first time I'm wrong...
