Yep. Compare the two photos.
In the top photo, this remnant taken from the rubble, we see evidence of at least 3 floors compressed into a chunk less than 3 feet in depth.
The red arrows indicate the remains of concrete floor slabs. The blue arrows indicate truss rods, mostly likely the triangular support rods, and the orange arrows indicate remains of the metal floor pans and support flanges. The bottom orange arrow points to a main truss beam.
I've heard the term 'meteorites' used to describe some of the 'congealed' lumps of debris. These conglomerations of building remnants which have been saved should be made available for testing for residues--of nanothermite and other explosive substances. As things are now, NIST admitted to not testing for explosives.
