Though no skeletal remains were discovered with the original Angaturama snout tip, one partial skeleton (MN 4819-V) from a different location may belong to the genus.
But since there is no overlapping material between the two specimens, direct comparisons cannot be made.
MN 4819-V comprises a largely intact pelvis, some dorsal (back) and caudal (tail) vertebrae, five sacral (hip) vertebrae, a partial right tibia and fibula (shin and calf bones), most of the right femur (thigh bone), and part of an ulna (forearm bone).
It also has the most complete hand known from a spinosaurid, including metacarpals, phalanges, one carpals, and one claw.
Like in all spinosaurids, the claw of the first finger (the "thumb") was enlarged.

The pelvic bones are well-preserved, with the right side better articulated than the left.
The fused sacral vertebrae are still attached to the pelvis, which lacks the distal ends of both of its pubic bones and ischia (lower and rearmost hip bones).
The ilium (main hip bone) is 55.3 cm (21.8 in) long.
The preacetabular ala (front expansion) of the ilium was curved on the bottom and was somewhat shorter and deeper than the postacetabular ala (rear expansion).
The preacetabular ala were somewhat enlarged at the front, in contrast to the more slender condition of the postacetabular ala.
The brevis fossa (groove at the bottom of the postacetabular ala) was concave, as was the rear margin of the ischium.
The pubis bore a relatively large and almost closed obturator notch, an indentation in the lower margin of the rear part of the bone that allowed for the passage of the obturator nerve.
The upwards projecting neural spines of the sacrum were elongated, as is typical in spinosaurs.
In life, these would have been covered in skin, forming a "sail" down the animal's back.
MN 4819-V is distinguished from Suchomimus due to its longer and shallower ilium with a less curved upper margin, and from Baryonyx by having a more developed obturator process, a blade-like structure on the bottom of the ischium.
