A towering extraterrestrial dinosaur stands majestically against a star-filled sky, its iridescent scales shimmering in cosmic hues of green and purple. The creature's elongated neck and tail are adorned with bioluminescent patterns that pulse gently, casting ethereal glows on the lush alien vegetation surrounding it. Its eyes, large and intelligent, reflect the mysteries of distant galaxies. The raw, untamed beauty of this otherworldly beast is both ancient and futuristically advanced, blending prehistoric earthiness with celestial splendor.
