RRRR newly discovered series, pre-Islamic Sumatra, c.1200-1500, Srivijaya or Majapahit Empire?

Stylized lion bust facing left with a raised front paw, above an umbrella as a simple cross or T-shape, with an outer border of dots // Stylized lion facing left, standing on a dead man. 15mm, 3.26 grams. Mint of Muara Kumpeh?. Cf. Zeno 310216.

This coin belongs to a newly discovered (and not-yet-published) pre-Islamic series, called the "Jambi lion" series. They seem to originate from a medieval port site not far from Jambi in Sumatra. This port site is known as Muara Kumpeh (today the village of Suak Kandis) and lies at the confluence of the Batanghari River and a tributary, the Kumpeh River. A few coins are listed on Zeno (a double unit, Zeno#310218, a full unit, Zeno #310220, 310219,  and half unit in a very poor state of preservation, Zeno #310216). The coin for sale here is superior to either example on Zeno. This series is broadly attributed to the pre-Islamic maritime Empires, and archaeological evidence places it in c.1000-1350 CE, so it might belong to Srivijaya or Majapahit Empires.
