Facts About the Prehistoric Suchomimus You Did Not Know

The precise timing and causation of the extinction event of the Suchomimus remain uncertain within the current body of research.

All extant specimens have been identified as originating from the Early Cretaceous period, specifically estimated to have existed between 125 and 112 million years ago.

This particular dinosaur exhibited a distinct dietary preference for fish, which is comparable to the feeding habits observed in the Spinosaurus.

The hypothesis put forth by scientists posits that the dietary regimen and the limited availability of sustenance played a role in the challenges faced by the organism in its quest for survival.

The potential reason for the extinction of the Suchomimus could be attributed to its failure to adapt to shifting food sources.


How Do I Describe the Suchomimus?

The estimated length of Suchomimus ranges from approximately 31 to 36 feet, with a corresponding weight estimate of 3 to 5 tons.

This particular Spinosaurid specimen exhibited a somewhat higher size compared to other members of its taxonomic group, however, it did not attain the same magnitude as the Spinosaurus.

The organism possessed an elongated appendage extending from its posterior region, which facilitated equilibrium while it engaged in bipedal locomotion and maintained a forward-leaning posture.

The neck of the subject in question exhibited a reduced length and a substantial development of musculature.

The specimen had a pair of forelimbs that were comparatively less in length when compared to its hind limbs.

However, it is plausible that these forelimbs possessed the capability to manipulate smaller objects, potentially including other members of the dinosaurian taxon.

The presence of sharp claws on their forelimbs implies that these organisms likely employed them for inter-animal conflict or for the purpose of dismembering prey.

The spinal column of this organism exhibited extended neural spines, which potentially served as support structures for sail-like formations.

The aforementioned features were predominantly located along the dorsal region.

The cranial structures of the subject species were comparatively smaller and less developed in comparison to those observed in Spinosaurus, albeit bigger in size when compared to the cranial structures of Baryonyx.

It is postulated by researchers that the Suchomimus would have possessed comparatively diminished sails.

An alternative hypothesis posits that the animal in question may have been in an immature stage of development, with the sails undergoing further growth and maturation when it approached adulthood.

The Suchomimus is characterized by its prominent elongated snout, reminiscent of crocodilians, positioned at a notably lower level than its eyes.

The length of the snout reached up to four feet, constituting a substantial proportion of its overall body size.

This particular dinosaur possessed a total of 122 teeth. Despite their pointed appearance, the objects in question lacked sharpness or serrations.

One plausible explanation for the dietary habits of Suchomimus, as posited by experts, is its likely inclination towards a pescatarian diet.

Additionally, the specimen possessed a robust secondary palate within its oral cavity, which likely facilitated enhanced manipulation and retention of piscine prey.

How Do I Describe the Postcranial Skeleton of the Suchomimus?

The neck exhibited a somewhat abbreviated length, yet displayed robust musculature, as seen by the prominent epipophyses, which serve as attachment sites for neck muscles.

Approximately sixteen dorsal vertebrae were present. The dinosaur species known as Suchomimus possessed notably elongated neural spines, which were blade-shaped upward extensions located on the vertebrae.

These neural spines were particularly enlarged towards the posterior end of the dinosaur’s body.

The sacral vertebrae, consisting of five segments, were observed to possess the greatest length. The extension of these anatomical formations persisted until the midpoint of the caudal region.

The spines perhaps supported a dermal structure, such as a crest or sail, which was positioned at its maximum height over the hips.

This structure was comparatively lower and extended further towards the posterior region than the sail of Spinosaurus, where the greatest point was observed over the dorsal vertebrae.

The aforementioned condition had a decrease in Baryonyx. The furcula had a V-shaped structure, which serves as an indicator of a tall and slender trunk.

The scapula possessed a quadrilateral acromion, which served as the point of attachment for the clavicle, also known as the collarbone.

The humerus, which refers to the upper arm bone, exhibited a substantial and sturdy structure.

In terms of non-spinosaurid theropods, its size was comparable only to that of Megalosaurus and Torvosaurus, featuring powerful upper corners.

The humerus exhibited a prominent bony protuberance located superior to the condyle, which made contact with the hook-shaped radius, a bone situated in the forearm.

Consequently, the ulna bone in the lower arm exhibited significant development, characterized by a substantial olecranon, which is an upper process that is distinct from the shaft.

This remarkable characteristic is shared with the dinosaur species Baryonyx.

The robust muscular structure of the arm facilitated the development of substantial hand claws, with the first digit, sometimes referred to as the “thumb,” being the most prominent, measuring 19 centimeters (7.5 inches) in length.

The only known metacarpal bone of the hand is the third one, which exhibits a sturdy and well-defined structure. The ilium, which is the primary bone of the hip, exhibited a superior position within the pelvis.

The pubis, also known as the pubic bone, exhibited a broader anterior surface compared to its lateral surface.

Furthermore, its distal end, oriented towards the front, was characterized by a flattened and rectangular shape, featuring a short flange along the midline.

This is in contrast to the more enlarged boot-like morphology observed in other theropods.

The ischium, which is the hip bone located in the bottom and rearmost region, exhibited a rather small obturator flange. The holotype had a straight and sturdy femur, measuring 107 cm (42 in) in length.

The lesser trochanter exhibits a distinct plate-like morphology. The ascending process of the astragalus in the ankle was found to be comparatively taller than that observed in Allosaurus.


How Do I Describe the Behaviour of the Suchomimus?

Where Does the Suchomimus Live?

The species known as Suchomimus inhabited the Early Cretaceous Period, namely over a time span ranging from 125 to 112 million years in the past.

The organism in question inhabited the geological interval spanning from the Aptian epoch to the Albian epoch.

The investigation involves the examination of rock formations and silt in the vicinity of Suchomimus fossils in order to ascertain their precise temporal context.

These prehistoric creatures inhabited the region that is now known as Niger, located in the north-central part of the African continent.

A fossilized skeletal remains were unearthed within the geological stratum known as the Elrhaz Formation.

The rock formation in question can be traced back to the Early Cretaceous period, some 112 million years in the past.

Researchers suggest that the geological composition of the minerals discovered at the site indicates an inland freshwater ecosystem during the temporal existence of Suchomimus.

The presence of rivers and floodplains likely facilitated the availability of sustenance for Suchomimus.

Additional fauna that thrived in the aforementioned ecosystem encompassed the concomitant theropod Kryptops, herbivorous organisms belonging to the Iguanidontia clade, and the ancestral precursors of crocodiles, known as Crocodylomorphs.

What Does the Suchomimus Feed On?

It is quite probable that Suchomimus predominantly consumed fish due to its distinctive elongated snouts. The attributes of the object facilitated their ability to successfully capture fish.

The aforementioned features encompassed the presence of well-developed forelimb claws, which were ideally suited for grasping piscine prey.

The presence of a robust secondary palate enabled them to retain live fish within their oral cavity during the process of ingestion. The Baryonyx, a similarly related species, was documented to have a piscivorous diet.

The paleontologists have also discovered the presence of fish scales within the stomachs of these specimens.

Based on the available information and the presence of similar anatomical characteristics, it is postulated that Suchomimus likely possessed a comparable dietary preference.

The presence of light and hollow bones in Suchomimus may have posed challenges for submerging itself in water for the purpose of hunting prey.

There is a higher probability that fish were discovered in shallower aquatic environments. Dental remains of dinosaurs provide valuable insights to scientists regarding the dietary preferences of these creatures.

The identification of a complete mandible containing dentition had a pivotal role in elucidating the dietary preferences of the Suchomimus.

The dental structures had a pointed morphology, albeit lacking a distinct degree of sharpness. Additionally, these dinosaurs did not possess the characteristic serrated edges commonly observed in carnivorous species.

The prevailing consensus among academics is that Suchomimus did consume a certain amount of meat, with a higher likelihood of engaging in scavenging behavior rather than actively hunting.

The dental structures possessed by these organisms were insufficiently developed to administer a lethal strike against the majority of dinosaurs inhabiting that era.


What are the Predators of the Suchomimus?

The possession of huge claws likely conferred a defensive advantage upon Suchomimus in its ability to ward off prospective predators; nonetheless, it remained susceptible to predation.

The specimen has considerable size, rendering it a formidable target for predation, although lacked the presence of serrated dentition observed in several other dinosaur species.

The perpetual risk of resource competition posed a significant challenge to all dinosaurs, Suchomimus included.

Although it is plausible that Suchomimus had the capacity to consume both fish and meat, it is conceivable that a change in the availability of food sources would have posed significant challenges to its survival.

The dietary preferences of this dinosaur were more specialized in comparison to other dinosaurs that either had longer lifespans or underwent adaptive changes.

The length of Suchomimus was estimated to be approximately 31-36 feet, while its weight ranged between 3 and 5 tons.

Certain experts argue that the comparatively diminutive Baryonyx may indeed represent a juvenile specimen of the larger Suchomimus.

Nevertheless, the precise age of the holotype specimen remains undetermined, hence introducing ambiguity regarding whether this size estimation represents its greatest potential.

Suchomimus is classified within the Theropoda lineage, among other members of the Spinosaurids. Additional theropods of significance include the Tyrannosaurus rex and the Velociraptor.
