Iguanodon bernissartensis

Reptilia

Taxonomy
Iguanodon bernissartensis was named by Boulenger (1881). Its type specimen is IRSNB 1534, a skeleton, and it is a 3D body fossil. Its type locality is Sainte-Barbe coal mine, Bernissart, which is in a Barremian/Aptian lacustrine - small claystone/bituminous coal in the Sainte-Barbe Clays Formation of Belgium.

It was synonymized subjectively with Iguanodon mantelli by Hooley (1912) and Kuhn (1964).

Diagnosis
ReferenceDiagnosis
L. Dollo 1882Skull twice as long as wide, measuring around 65 centimeters. Nares are projected over only one-third of the lower jaw. Greater diameter of the orbit vertical. Temporal fossa largely open. Minimum width of the scapula contained nearly six times in its maximum length. Coracoid furnished with an indentation communicating laterally with the exterior. Sternal plates wide and strongly interiorly indented. Forelimbs representing nearly two-thirds of the hindlimbs. Six vertebrae in the sacrum. Preacetabular projection of the ilium equal to about one-third of the total length of this bone. Pubis long, massive, and straight. Third trochanter situated near the lower third of the femur. Total length 8 to 10 meters.
D. B. Norman 1980Maximum length 11 metres. Double supraorbitals (palpebrals). Number of vertical tooth rows in maxilla and dentary variable, with a maximum of 29 in the maxilla an 25 in the dentary. Sacrum composed of eigth fused vertebrae. Scapula, inexpanded distally, proximal region of shaft considerably thickened. Intersternal ossification present. Forelimb long (approx. 70% of length of hindlimb) and stroutly constructed. Carpals co-ossified. First metacarpal fused to carpals. Phalangeal count of manus: 2, 3, 3, 4, 4; first phalanx of digit I consists of a thin, warped plate of bone, which lies in a shallow recess in the proximal surface of the ungual phalanx. The latter has the form of a long, curved, conical spine which can freely articulate against the fused carpometacarpus. Ungual phalanges of digits II and III are broad, rather hoof-like and twisted longitudinally. Hind end of ilium pointed in lateral aspect, with a broad brevis shelf. Anterior ramus of the pubis relatively narrow, proximally transversely flattened, but with a moderately expanded distal end. Three distal tarsals present. Metatarsal I reduced and transversely flattened, matatarsal V absent.
G. S. Paul 2007Adults large at 11 m, mass about 3+ tonnes. Overall massively constructed. Accessory palpebral present. Quadrate shaft straight. Maximum tooth positions 29 in maxila, 25 in dentary. Neural spines of dorsals, sacrals, and caudals short. Posterior dorsal centra anteroposteriorly compressed. Eight fused sacrals. Scapula consistently broad along length of blade. Acromion process placed proximally and directed anteriorly. Coracoid large relative to scapula. Forelimb 75% of hindlimb. Deltopeectoral crest of humerus modest sized. Manual spike and other unguals large. Prepubis shallow. Femoral fourth trochanter ventrally spiked.
G. S. Paul 2008Overall massively constructed. Premaxillary tip to anterior orbital rim/latter to paraoccipital process tip length ratio ~1.1; dentary pre-coronoid process length/minimum depth ratio under 4. Maxillary process of premaxilla shallow. Dorsal apex of maxilla set posteriorly. Antorbital fossa and fenestra *moderate in size. Lacrimal short, does not contact nasal. Accessory palpebral *present. Posterior border of occiput deeply indented. Lateral temporal fenestra large. Posterior portion of jugal short. Quadratojugal tall. Quadrate tall, transversely broad, shaft straight, lateral foramen set low, dorso-posterior buttress *very large. Diastema absent. Maximum tooth positions *29 in maxilla, *25 in dentary. Dorso-sacral/hindlimb length ratio w1. Posterior dorsal centra antero-posteriorly compressed. Neural spines of dorsals, sacrals and caudals short. *8 fused sacrals. Scapula blade *consistently broad, *base very broad, *acromion process placed dorsally and directed anteriorly. Coracoid large. Forelimb *~70% length of hindlimb. Deltopectoral crest of humerus *proximally located and modest in size. Olecranon process large. Manus *massive, phalanx 1 of digit I *present, pollex spike and other unguals large. Anterior process of ilium *much shorter than main body, main body shallow, posterior acetabular body *long. Prepubic process of pubis shallow. Femoral shaft straight. Metatarsal I present, II long.
F. J. Verdú et al. 2015Potential autapomorphies of I. bernissartensis according to Norman (2012): (I) two palpebral bones; (II) 29 maxillary and 25 dentary teeth; (III) posterior dorsals remain tall-sided, but broaden to produce an almost circular shape (indented dorsally by the neural canal), giving rise to a broadly heart-shaped articular face when viewed axially; (IV) scapular blade tends to be comparatively slightly expanded distally and modestly recurved in lateral view (...), with the proximal portion of the shaft expanded and massive adjacent to the scapulocoracoid suture and humeral glenoid; (V) an “intersternal ossification” is commonly preserved in the midline of the upper chest in the space between the coracoids and sternal bones; (VI) forelimb at least 70% the length of the hind limb, and robustly constructed; (VII) carpals heavily co-ossified and supported by ossified ligaments; (VIII) phalangeal count of the manus: 2:3:3:2:4; (IX) the first phalanx of digit 1 of the manus is preserved as a flattened and warped plate that lies in a recess at the base of the pollex ungual; (X) united phalanx 1–pollex can articulate freely (and transversely) against the roller-like articular surface of metacarpal 1; (XI) three distal tarsals are present; (XII) metatarsal I reduced to a transversely flattened splint that lies obliquely against the shaft of metatarsal II.
An additional potential autapomorphy of I. bernissartensis might be an ischium with a distal end small compared to its proximal end (ratio 0.27 in IRSNB 1534 [holotype] in Fig. 67 of Norman (1980)).
