The hollow crest really pulls the whole figure together, and I love how it captures the acoustic resonance idea from the description—it makes the head look both scientific and alive. It’s a solid piece that sparks a fun conversation about dinosaur hearing every time someone sees it.

The crest design is really impressive, and it's fascinating how it functions for acoustic resonance. I've spent a good amount of time just examining the detail and learning about its purpose.

I was curious about the acoustic resonance claim, so I tested it myself—the crest actually does amplify sound in a noticeable way. It’s a clever design that makes learning about dinosaur hearing fun for both kids and adults.
