TWO WAYS TO PICTURE THE PAST
Compare the evidence with the familiar movie image. The illustrations are not to a shared scale.
Limaysaurus skeletal restoration photographed in Copenhagen. Missing anatomy and pose are restored. The source gives no single inventory number or verified individual life stage; the mount is not the deliberately scaled 10.9 m biomechanics model. [1]

MEET THE ANIMAL
Limaysaurus was a long-necked sauropod from Late Cretaceous Patagonia in Argentina. Its species was once called Rebbachisaurus tessonei before receiving its own genus name. The renaming keeps the Argentine animal distinct from Morocco's Rebbachisaurus. A scientific name can change while the same inventory-numbered bones remain the reference, without turning a change of name into a change of specimen. [D2]
One published body model was scaled to about 10.9 metres for a biomechanics thought experiment. The animal was used as an illustrative prey example, not as evidence of a fossilized hunt. The model's size depends on its deliberately chosen scale. It should not be confused with a measured complete specimen, a mature maximum or proof that the imagined predator encounter really happened. [D6]
A study of fossil eggs discussed Limaysaurus among possible producer groups but identified the eggs only within the broader Neosauropoda. Without a genus-specific embryo, those eggs cannot securely establish Limaysaurus nesting behavior. General sauropod reproductive evidence may suggest questions to investigate, while leaving egg number, incubation conditions and parental care unresolved for this particular dinosaur. [D7]
PREHISTORIC ANIMAL DOSSIER
The animal, the evidence, and the questions still open.
Renaming and revised referrals narrow the evidence to the actual genus. Body models, abdominal stones and quarry associations each answer different questions and carry distinct uncertainties. [D2]
Profile scope: Genus profile centered on Limaysaurus tessonei, especially type MUCPv-205. MUCPv-153 and MUCPv-206 are separate individuals; older Lohan Cura referrals now belong to Comahuesaurus. [D1] [D3]
Source supported identifies a description documented by the cited source. Inferred marks a reconstruction or functional estimate. Debated marks competing interpretations. Not established means the sources reviewed for this dossier do not support a firm conclusion; it does not mean a behavior never occurred.
A size reference is an estimate, not a population range. Nesting evidence does not by itself establish courtship, mate choice, or lifelong pairing.
10.9 m; deliberately scaled comparative model
Henderson and Nicholls scaled a reconstructed body to an illustrated prey scenario. This is not MUCPv-205’s measured length, an established life stage or an adult maximum; the source does not document a real intercontinental predator encounter. [D6]
About 7.4 tonnes; type-based volume model
Paul lists MUCPv-205 under its historical Rebbachisaurus name. This restored-volume model concerns Limaysaurus, not R. garasbae. It differs from the smaller illustration-scaled model and does not define an adult population range. [D5]
Plant feeding inferred; abdominal stones reported
Teeth are consistent with herbivory. Six rounded stones were described in the type’s abdominal region, two against ribs; interpreting them as swallowed stones does not by itself prove a gastric mill or identify eaten plants. [D1]
Cenomanian Candeleros Formation, Patagonia
L. tessonei is retained from Argentina’s Cenomanian Candeleros Formation. Former Early Cretaceous Lohan Cura material belongs to Comahuesaurus, so it does not extend this species’ age or locality range. [D2] [D3]
Quadrupedal sauropod reconstruction
Limb and axial bones support four-legged reconstruction. Posture and missing regions are restored; a volume model does not establish walking speed or a fixed neck angle. [D1]
Tall, undivided spines and an arched posterior skull
The original description documents tall cervical and dorsal neural spines rather than paired branches. Cranial remains principally document the posterior skull, leaving much of the muzzle to comparative restoration. [D1]
Not established here
A Sanagasta egg study listed Limaysaurus among possible producer clades but retained a broad Neosauropoda attribution. No genus-specific embryo identification establishes these eggs, geothermal nesting or parental care for Limaysaurus. [D7]
Not established here
Focused searches did not establish sex-specific anatomy, calls, mate choice or mating displays. Vertebral height alone does not demonstrate a reproductive function.
Not established here
The original description includes separate adult-labeled individuals, not an observed herd. A multi-individual Lohan Cura assemblage once referred to Limaysaurus is now Comahuesaurus and cannot supply this genus’s social evidence. [D1] [D3]

THE STORY IN THE FOSSILS
The name changed while the inventory number stayed the same: MUCPv-205 anchors the renamed species. Whole-genus Rebbachisaurus and Rayososaurus remain distinct despite older species combinations. [2] [4]
The 10.9 m body model was created for a biomechanics thought experiment. It should not be read as a fossilized hunt or paired with the larger type-based mass as one measured individual. [6]
The dossier identifies the scope of each reference estimate. A mount, an individual fossil and a species-wide adult range are different measurements. Comparison metrics remain unavailable where adult scope has not been established. Unknown does not mean zero.

KEEP EXPLORING
Rebbachisaurus garasbae
Rebbachisaurus was a Moroccan sauropod with towering back vertebrae. Its head and much of its complete silhouette remain reconstructed.
Rapetosaurus krausei
Rapetosaurus was a Malagasy titanosaur. Its famous Field Museum skeleton belonged to a growing youngster.
Isisaurus colberti
Isisaurus was an Indian titanosaur whose partial skeleton preserves distinctive neck vertebrae, shoulders and forelimbs.
