LOVED (8)

01Stunning visual impact when fully built; models look like museum pieces or model kits from a distance
02Three distinct models (T-Rex, Triceratops, Pteranodon) in one box with virtually no build repetition
03Articulated posing in heads, tails, and jaws giving the fossils a sense of life on display
04Excellent piece-to-price ratio at approximately $0.066 per piece for 910 pieces
05Light brown accent colors between white bone pieces add visual contrast and definition
06Interesting building techniques used to achieve curved and exotic fossil shapes
07Impressive overall size when completed; larger than expected from the box art
08Inclusion of minifigures and accessory tools described as a bonus by multiple buyers

CRITICIZED (6)

01T-Rex head does not stay up reliably due to a single ball-socket connector under the heavy head
02Stickered nameplates rather than printed, which disappointed several reviewers
03Fragile rib sections on the T-Rex and Triceratops move easily and can fall out
04All-white part palette can make piece sorting and identification difficult during the build
05Limited playability; the fossils are display models and not suited to hands-on play for young children
06Models are mounted on fixed stands, restricting free repositioning

JANG's LEGO Reviews

The Brothers Brick

Brickset Reviews

Ecosystem

Previous LEGO Pteranodon sets — Bones model is larger but overall compatible in scale; provides more detail and articulation.

Previous LEGO Triceratops sets (larger recent versions) — Significantly larger than earlier versions; better engineered and more scientifically accurate.

Previous LEGO T-Rex sets (modern color variants) — Much larger in overall size; superior articulation and building techniques.

Museum wooden fossil models (childhood reference) — Much better because it's so 3D; captures the spirit but with superior execution.

✓Three separate builds provide variety and extend play/display value

Key Cons

✕Misleading set name—includes a pterosaur, which is not a dinosaur, perpetuating misconceptions
✕Triceratops appears to be mislabeled (likely Styracosaurus based on frill spines), contradicting fossil evidence

Value drivers

The Brothers Brick: The overmolded paleontologist with unique brown boots and mustache may appeal to collectors, and the minifig skeleton is a unique pun

Brickset Reviews: Paleontologist minifigure with rare head piece (from 70632 Quake Mech) and scarce dark brown hair piece (only in four earlier sets). LEGO Sapiens skeleton minifigure also unique to set.

Exclusivity

JANG's LEGO Reviews: LEGO Ideas fan submission converted to retail. Wide retail availability (mentioned as stocked in LEGO stores). Not exclusive.

The Brothers Brick: LEGO Ideas exclusive based on fan submission; set was to go on sale November 1st, 2019

Resale

JANG's LEGO Reviews: Not explicitly stated. Reviewer notes strong retail sales and broad appeal (adults and kids alike) but does not forecast secondary market performance.

The Brothers Brick: Not explicitly stated, but the reviewer notes this is a 'fairly substantial set' with good parts value, suggesting potential for aftermarket appeal

Minifigures & Standout Parts

In this set (2)

Paleontologist

LEGO Sapiens

Standout parts (per reviewers)

Horn/claw pieces used as ribs
Repurposed from other sets for rib cage construction; long mold appears older and fits loosely, causing offset issues and requiring careful handling.
Tan connector piece (horse carriage part)Value
Used to attach ribs at subtle angle; tan color is uncommon/historical in LEGO palette; allows angled rib attachment without additional spacers.
Eye detail pieces (Pteranodon)
Reviewer's favorite aspect of the small model; shaped pieces create realistic eye appearance.
Opened head design (T-Rex, Triceratops)
Multiple cavities and openings in skull structure for scientific accuracy and visual appeal; suggests bone structure through negative space.
Bone/fossil tiles and modified plates
Set includes many small one-by-one, one-by-two, and modified tiles; extras included in spare parts.
Tan horse harness (used for ribs attachment in T. rex and Triceratops)
Repurposed from common elements to create anatomical rib cage structures

What Owners Say

The Dinosaur Fossils set is near-universally beloved as a stunning, creative display piece with clever building techniques, minimal repetition, and broad appeal across ages, with only minor complaints about the T-Rex head not staying up and the all-white color palette making piece sorting tricky.

COMMON PRAISE

+Incredibly clever and varied building techniques that produce realistic-looking fossil skeletons surprising even experienced builders
+Minimal repetition across three distinct models keeps the build engaging from start to finish
+Exceptional display quality, with many reviewers noting visitors cannot tell at a glance that it is made from LEGO
+Movable heads and tails on the models allow for custom posing and add interactive value

COMMON COMPLAINTS

−T-Rex head is frequently cited as too heavy and does not stay in position without support
−Nearly all-white color scheme makes sorting and identifying pieces during the build more difficult than usual
−Some rib sections on the Triceratops and T-Rex have weak connections that are fiddly to position and can shift over time
