> 1) what parts were included in holotype specimen of Baryonyx walkeri.

Baryonyx walkeri:
BMNH R9951 (HoloType) consisting of conjoined premaxillae, conjoined vomers,
anterior part of left maxilla, conjoined nasals, left lacrimal, left
prefrontal, left postorbital, anterior end of braincase (right frontal,
right parietal, right orbitosphenoid, right laterosphenoid) posterior end of
braincase together with occiput (both prootic, both opisthotics,
basisphenoid, supraoccipital, both exoccipitals, basioccipital) left jugal,
both quadrates, both dentaries, both splenial, right surangular, both
angulars, right coronoid, some upper teeth and many isolated teeth of
unknown position, axis and 4 cervical vertebrae, 12 dorsals, 3 or 4 basal
caudals, 3 distal caudals, one axial rib, three cervical ribs, dorsal ribs,
abdominal ribs, sternum, both scapulae, both coracoids, both humeri, left
radii, left ulna, left pollex with ungual, left digit II or digit III,
isolated phalanges of bith sides, right ilium, both pubes, left ischium,
proximal end of left femur and distal end of right femur, right fibula,
right calcaneum, metatarsal fragments, 1 pedal ungual.

NOTE: Sereno (1998) in his Suchomimus's description offer an alternative
identifications for several cranial elements in the HoloType of Baryonyx
walkeri. The bone identified as the left postorbital, left jugal, right
atlantal neural arch, and left angular as the posterior portion of the right
surrangular, right prearticular, central body of the left pterygoid and
right angular respectively, Sereno repositioned all this bone in his cranial
reconstruction (fig.2 C and D pag.1299).

I'm not sure about this, Spinosaurus cf. aegyptiacus:
IMGP 969-3 isolated teeth and two jaws fragments

> 3) what has been found spinosaurus maroccanus.

Spinosaurus maroccanus:
NMC 50791 (HoloType) median cervical vertabra, NMC 50532 (referred
specimens) dentary fragments NMC 41768 (referred specimens) median cervical
vertebrae, NMC 50813 (referred specimens) dorsal neural arch.
MNHN SAM 124 (referred specimens) rostrum containing both premaxillae,
maxillae, vomers and fragment of rght dentary, MNHN SAM 125 (referred
specimens) fragement of premaxilla, MNHN SAM 126-127 (referred specimens)
centra of 2 cervical vertebrae MNHN SAM 128 (referred specimens) neural arch
of dorsal vertebrae.

Hope this help
