I get error CS0119 and I don't know why?

I keep getting error CS0119: Expression denotes a 'type', where a variable, value, or method group was expected when writing this script. Any help would be appreciated. This is for line 13 of the code

     void FixedUpdate ()
     {
         if (dead) 
         {
             return;
             GetComponent<Rigidbody2D> ().AddForce (Vector2.up * upSpeed);
             didFlap = false;
         }
         if (GetComponent< Rigidbody2D> ().velocity.y > 0) {
             transform.rotation = Quaternion.Euler (0, 0, 0);
         } else 
         {
             float angle = Vector3(Mathf.Lerp (0, -90, (-Rigidbody2D.velocity.y / 3f)));
                 transform.rotation = Quaternion.Euler(0,0, angle);
         }
     }
 
     void OnCollisionEnter2D(Collision collision)
     {
         if (godMode)
             return;
         GetComponent<Animator>() .SetTrigger ("Death");
         dead = true;
         deathCooldown = 0.5f;
     }
 
 }
