Edmontosaurus annectens
Part of the CRESTS & HERBIVORES Exhibit
Late Cretaceous Period, approx. 69-66 million years ago
1:3 Scale Skull Replica
SPECIMEN PROFILE
Edmontosaurus annectens was one of the final and most widespread hadrosaurid species of Late Cretaceous North America, living in the closing stages of the dinosaur era. It occupied extensive floodplain and coastal plain environments, often alongside other large herbivores and apex predators such as Tyrannosaurus rex.
While closely related to Edmontosaurus regalis, this species is distinguished by subtle but important differences in skull proportions and overall body robustness. E. annectens exhibits a more elongated, “duck-billed” snout profile and a generally more streamlined cranial architecture, suggesting refinements in feeding mechanics and grazing efficiency. It is also one of the best-represented hadrosaurs in the fossil record, with multiple well-preserved skeletons providing insight into growth stages and population structure.
Like its relatives, it lacked prominent cranial crests and instead relied on sheer abundance, herd behavior, and efficient plant processing to dominate its ecological niche.
COLLECTOR & CURATOR NOTE
A late-surviving, highly refined hadrosaurid distinguished from its cousin E. regalis by its more elongated skull and streamlined feeding adaptations—representing the final evolutionary phase of classic duck-billed herbivores.
CONSTRUCTION & DISPLAY
Scale
1:3, approx. 11.8 in or 30 cm
Fossil Finishes
Aged Bone: A weathered bone-white aesthetic, evoking exposed skeletal remains and museum restorations.
Canyon: Warm earth tones and terracotta hues, inspired by fossil beds such as Picketwire and Mill Canyon.
Fossilized: Deep browns and near-black coloration, replicating the mineral-rich preservation seen in authentic fossil specimens.
Specimen Format
Unmounted study specimen: A standalone skull, ideal for shelves, cases, or custom display setups.
Desktop-mounted display specimen: Presented on a handmade desktop stand, crafted from wood with brass furnishings and a custom specimen placard — designed to elevate the specimen as a true exhibit piece.
